Below is a video tutorial on how to solve quadratic equation problems.

## Quadratic Equation Explanation

A quadratic equation is a polynomial of the second degree and is generally expressed in the following form:

^{2}+ bx + c = 0

where,

x represents an unknown or a variable and a,b & c are constants with a ≠ 0. If a = 0 the equation is linear.

## Quadratic formula

A quadratic equation with real or complex coefficients has two solutions, called *roots*. These two solutions may or may not be distinct, and they may or may not be real.

The roots are given by the quadratic formula

where the symbol " ± " indicates that both

are solutions of the quadratic equation.
