## What is the Discriminant?

The discriminant is a value calculated from the coefficients of a quadratic equation of the form *ax² + bx + c = 0*. It provides information about the nature of the roots of the quadratic equation. Specifically, it helps to determine whether the roots are real or complex, and if they are real, whether they are distinct or repeated.

## What is the Discriminant Calculator Website?

The Discriminant Calculator website is an online tool designed to perform calculations involving the discriminant of quadratic equations. It allows users to input the coefficients of a quadratic equation and quickly obtain the discriminant value along with insights into the nature of the roots.

## How to Use the Discriminant Calculator Website?

Using the Discriminant Calculator website is straightforward:

- Navigate to the Discriminant Calculator website.
- Input the coefficients of your quadratic equation (usually represented as
*a*,*b*, and*c*in the equation*ax*).^{2}+ bx + c = 0 - Click the 'Calculate' button.
- The website will display the value of the discriminant and interpret the nature of the roots.

## What is the Formula of Discriminant Calculator?

The formula for calculating the discriminant *D* of a quadratic equation *ax ^{2} + bx + c = 0* is:

`D = b`^{2} - 4ac

Where *a*, *b*, and *c* are the coefficients of the quadratic equation. The value of *D* helps in determining the nature of the roots:

**If D > 0:**The quadratic equation has two distinct real roots.**If D = 0:**The quadratic equation has exactly one real root (or two identical real roots).**If D < 0:**The quadratic equation has two complex conjugate roots.
