# How to solve a quadratic equation?

**Answiki**on 09/27/2022 at 05:24:37 PM UTC

A **quadratic equation** can be solved in two steps (calculation of **discriminant** and **roots**). The solutions of this equation are called **the roots**. A quadratic equation may have one or two roots.

Let's consider the following equation in its standard form:

** Step 1.** Calculate the discriminant given by the following formula:

** Step 2.** Calculate the roots according to the sign of the discriminant (

**Case 1:** if

**Case 2:** if

**Case 3:** if

__Example:__

Let's consider the following quadratic equation:

Parameters of the equation are:

The discriminant is given by:

The discriminant is positive, thus the quadratic equation has two distinct real roots given by:
