Take a quadratic equation mix it with an inequality and graph it- the result is a quadratic inequality.  These problems take time so don’t rush to graph these quadratic inequalities because it’s easy to make mistakes.  The key is to first know how to graph a quadratic equation and linear inequality. The notes and example below will certainly help you….good luck!



some key topics that involve quadratic inequalities:

* solutions region
* solutions and roots
* quadratic formula
* linear and compound inequalities
