Solve polynomial inequalities.
Solve rational inequalities.
We will use a combination of algebraic methods and graphical methods to solve polynomial inequalities and rational inequalities.
Just as a quadratic equation can be written in the form , a quadratic inequality can be written in the form , where is , or . Here are some examples of quadratic inequalities:
When the inequality symbol in a polynomial inequality is replaced with an equals sign, a related equation is formed. Polynomial inequalities can be solved once the related equation has been solved.
