Quadratic equations are an integral part of mathematics which has application in various other fields as well. Hence we have made this site to explain to you what is a quadratic equation. After understanding the concept of quadratic equations, you will be able to solve quadratic equations easily.

Now let us explain to you what is a quadratic equation. It is a mathematical equation with the highest power of 2. Here x represents the unknown value, and a, b and c represents known numbers. The solutions of quadratic equations can be using the quadratic formula. There are other methods of finding the solutions of quadratic equations too, such as factoring, completing the square, or graphing. Since quadratic equations have the highest power of 2, there will always be two solutions for x that would be coming up.

These values of x that satisfy the equation, are called roots or zeroes of the equation. Hence a quadratic equation will always have two roots or solutions. Here through this article, we have tried to explain to you all concepts of quadratic equations. If you are a student, then learning about these concepts is very important since it will help you solve the problems at school. It is an important concept which has a wide range of application in fields such as physics, chemistry, engineering, etc.

We have discussed with you the general format of the quadratic equation. Now if you require to solve the quadratic equation, you have to use the quadratic formula. Any quadratic equation has two solutions or roots.

Here we have provided you with a table showing the quadratic formula, so it will be easy for you to memorize and apply it. A quadratic equation calculator is a special calculator, which is used to solve the complex quadratic equations.

While a scientific calculator might be used to calculate the roots of a quadratic equation, it is always not a convenient method.And that formula is:. For this post, I am assuming that you are aware of the basics of quadratic equations and know how to use the above mentioned formula.

Wikipedia can be daunting at times, so come back here as soon as you start feeling woozy. In this particular post, I am going to discuss ideas related to maxima and minima with respect to equations and quadratic equations in particular. The first thing that you need to understand is that a quadratic equation will either have a maxima or a minima but it cannot have both. The reason for that is, a quadratic equation is shaped like a parabola which is either open upwards or downwards.

The nature of the graph of the quadratic equation is decided by the co-efficient of x 2. If the co-efficient of x 2 is greater than 0, the parabola will be open upwards and hence it will have a minima. If the co-efficient of x 2 is less than 0, the parabola will be open upwards and hence it will have a maxima.

Once you have decided whether it will be a maxima or a minima the next task is to figure out two things:. Let us try to figure these values out with the help of an example of both types i. To make things a little more complicated, you might get a question in which the quadratic equation is in the denominator. It is sometimes also referred to as the rational function.

Editor Picks.Quadratic equations are actually used in everyday life, as when calculating areas, determining a product's profit or formulating the speed of an object. The letter X represents an unknown, and a b and c being the coefficients representing known numbers and the letter a is not equal to zero.

People frequently need to calculate the area of rooms, boxes or plots of land.

An example might involve building a rectangular box where one side must be twice the length of the other side. For example, if you have only 4 square feet of wood to use for the bottom of the box, with this information, you can create an equation for the area of the box using the ratio of the two sides.

This equation must be less than or equal to four to successfully make a box using these constraints. Sometimes calculating a business profit requires using a quadratic function. If you want to sell something — even something as simple as lemonade — you need to decide how many items to produce so that you'll make a profit.

Let's say, for example, that you're selling glasses of lemonade, and you want to make 12 glasses. You know, however, that you'll sell a different number of glasses depending on how you set your price. So, to decide where to set your price, use P as a variable. You've estimated the demand for glasses of lemonade to be at 12 - P.

Using however much your lemonade costs to produce, you can set this equation equal to that amount and choose a price from there. In athletic events that involve throwing objects like the shot put, balls or javelin, quadratic equations become highly useful. For example, you throw a ball into the air and have your friend catch it, but you want to give her the precise time it will take the ball to arrive.

Use the velocity equation, which calculates the height of the ball based on a parabolic or quadratic equation. Begin by throwing the ball at 3 meters, where your hands are.

Also assume that you can throw the ball upward at 14 meters per second, and that the earth's gravity is reducing the ball's speed at a rate of 5 meters per second squared. If your friend's hands are also at 3 meters in height, how many seconds will it take the ball to reach her?

The answer is approximately 2. Quadratic equations are also useful in calculating speeds. Avid kayakers, for example, use quadratic equations to estimate their speed when going up and down a river. Assume a kayaker is going up a river, and the river moves at 2 km per hour. The total time is equal to 3 hours, which is equal to the time going upstream plus the time going downstream, and both distances are 15km.

Solving for x, we know that the kayaker moved his kayak at a speed of Kevin Wandrei has written extensively on higher education. His work has been published with Kaplan, Textbooks. About the Author. Copyright Leaf Group Ltd.Quadratic Formula Discriminant Disc.

But sometimes the quadratic is too messy, or it doesn't factor at all, or you just don't feel like factoring. While factoring may not always be successful, the Quadratic Formula can always find the solution. Practice The Quadratic Formula. The Quadratic Formula is derived from the process of completing the square, and is formally stated as:. Also, the " 2 a " in the denominator of the Formula is underneath everything above, not just the square root.

And it's a " 2 a " under there, not just a plain " 2 ".

Remember that " b 2 " means "the square of ALL of bincluding its sign", so don't leave b 2 being negative, even if b is negative, because the square of a negative is a positive. In other words, don't be sloppy and don't try to take shortcuts, because it will only hurt you in the long run.

Trust me on this! How would my solution look in the Quadratic Formula?

The corresponding x -values are the x -intercepts of the graph. Graphing, we get the curve below:. This can be useful if you have a graphing calculator, because you can use the Quadratic Formula when necessary to solve a quadratic, and then use your graphing calculator to make sure that the displayed x -intercepts have the same decimal values as do the solutions provided by the Quadratic Formula. Note, however, that the calculator's display of the graph will probably have some pixel-related round-off error, so you'd be checking to see that the computed and graphed values were reasonably close; don't expect an exact match.

I will apply the Quadratic Formula. Warning: The "solution" or "roots" or "zeroes" of a quadratic are usually required to be in the "exact" form of the answer. In the example above, the exact form is the one with the square roots of ten in it. You'll need to get a calculator approximation in order to graph the x-intercepts or to simplify the final answer in a word problem.

But unless you have a good reason to think that the answer is supposed to be a rounded answer, always go with the exact form. Just as in the previous example, the x -intercepts match the zeroes from the Quadratic Formula. This is always true. The "solutions" of an equation are also the x -intercepts of the corresponding graph.

It is very essential to learn quadratic equations, because it have wide applications in other branches of mathematics, physics, in other subjects and also in real life situations.

A polynomial of degree two is called a quadratic polynomial. When a quadratic polynomial is equated to zero, it is called a quadratic equation. A zero of a polynomial is that real number, which when substituted for the variable makes the value of the polynomial zero. In case of a quadratic equation, the value of the variable for which LHS and RHS of the equation become equal is called a root or solution of the quadratic equation.

There are three algebraic methods for finding the solution of a quadratic equation. Brahmagupta an ancient Indian Mathematician A. Later Sridharacharya A. An Arab mathematician Al-khwarizni about A.
