Quadratic equations are any equations having the form  , where represents an unknown, and  ,  , and represent known numbers such that .
The quadratic equation only contains powers of  that are non-negative integers, and therefore it is a polynomial equation, and in particular it is a second degree polynomial equation since the greatest power is two.
Quadratic equations can be solved by: - Factoring technique
- Square Root Technique
- Completing the Square Technique
- Quadratic Formula Technique
- Graphing Technique
