Solving Quadratic Inequalities |
|
|
You have learned many methods for solving quadratic equations. In this activity, you can extend your knowledge to quadratic inequalities. You can solve quadratic inequalities by first solving the
corresponding quadratic equation and then using one of several methods to determine what values make the inequality is true. |
