# Discriminant Calculator

The Discriminant tells about the nature of the roots of quadratic equation. In quadratic equation formula, we have $$b^2 - 4ac$$ under root, this is discriminant of quadratic equations.
There are three cases for discriminant:
if $$b^2 - 4ac = 0$$, then the roots of quadratic equations are real and equal.
if $$b^2 - 4ac > 0$$, then the roots are real but not equal
if $$b^2 - 4ac < 0$$, then the roots are not equal and are imaginary.

$$a x^2 + bx + c = 0$$
