### Definition of a Quadratic Equation

A quadratic equation is an equation involving the square of a number which is the highest power in the equation.

It is usually in the form:

ax2 + bx + c = 0

where a, b and c are numbers, and x is an unknown.

It is also sometimes called a second degree polynomial equation.

x2 + 7x + 4

2y2 - 28

4a 2 - ½ a + 15

The following equations are NOT quadratic expressions:
