# Math Definitions - Letter Q

### Chapters

A quadratic equation is a special type of algebraic equation in which the highest power of the variable (usually $x$) is $2$.

So, $x^2 - 2x + 5 = 0$ is a quadratic equation, but $x^4 - 17x^2 + 15 x - 9 = 0$ is not.

For example, $3x^2 + 17 x - 54 = 0$ is a quadratic equation.

Quadratic equations may have $0$, $1$ or $2$ solutions.
