# What is the quadratic formula used for?

A quadratic equation is an equation of degree 2.

## Answer: The quadratic formula is used to solve quadratic equations.

A quadratic equation is the form of ax^{2} + bx + c = 0, where a ≠ 0.

**Explanation:**

For any quadratic equation in variable x: ax^{2} + bx + c = 0, where a ≠ 0 and a, b and c are any integers, we find the value of x by the quadratic formula:

\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)

We can solve any quadratic equation with the help of quadratic formula especially the ones which are difficult to factorize.

It is also called **"Quadranator"** and can hunt down all the solutions of the quadratic equations.

(b^{2} - 4ac) is called the **"discriminant"** because it discriminates the quadratic equation solutions based on its sign.
