What is a Quadratic Inequality?
Note:
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 is a Linear Inequality?
A linear inequality is almost the same as a linear equation, except the equals sign is replaced with an inequality symbol. You'll find that a little more effort is needed to solve and graph a linear inequality, but it's nothing you can't handle! Check out this tutorial and get introduced to linear inequalities!

What's a Solution Set?
When an equation has two variables, the set of ordered pairs that are the solution to the equation are called the solution set to the equation. In this tutorial, you'll learn the definition of a solution set and see an example. Take a look!
