Background Tutorials

Solve quadratic equations having real solutions by factoring, taking square roots, completing the square, and applying the quadratic formula
- How Do You Solve a Quadratic Equation by Factoring?
  
  One of the many ways you can solve a quadratic equation is by factoring it. In this tutorial, you'll see how to factor a quadratic equation using the guess and check method of factoring. Then, use the zero product property to find the solution!
- What's the Zero Product Property?
  
  The zero-product property let's you split the product of factors into separate equations. Then, you can solve each equation to get the solutions to your original equation! Learn all about this very useful property by watching this tutorial.

- 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.
