### What is Meant by Quadratic?

In mathematics, the quadratic (also known as a quadratic equation) is defined as the polynomial equation with the highest order of degree 2. The standard quadratic equation is of the form ax+ bx + c = 0, where a, b, c are the coefficients, x is the variable, and a ≠ 0. The values of x are called the roots of the quadratic equation. The variable values can be found using the quadratic formula

Quadratic Equation Formula is,

$x =\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}$

The discriminant of the quadratic equation is given as:

D = b2 -4ac
