What is a Quadratic Inequality?

A quadratic inequality is just like a quadratic equation, except instead of an equal sign there's an inequality! Check out this tutorial to see the characteristics of a quadratic inequality and get some practice identifying them.
What are Critical Values?

The critical values of a quadratic inequality are also the x-intercepts of the corresponding quadratic equation. This tutorial provides a great explanation of the critical values of a quadratic inequality!
