Description:

 

1.  Find the greatest common factor of monomials.

2.  Factor simple quadratic equations using multiple methods.

3.  Solve quadratic equations by factoring.

In the last section, we examined how to solve a quadratic equation by graphing.  Recall that a quadratic equation is simply an equation that sets a quadratic expression equal to a value.  In this section, we will review the methods for factoring a polynomial and use the factored forms of quadratic equations to identify solutions.

Find the Greatest Common Factor (GCF) of monomials

One important skill is finding what monomials "have in common". We can then factor out these greatest common factors (GCF) to help solve equations.

Factoring Quadratics

Factoring quadratics is essential skill in many math classes. Take a bit of time to truly learn how to factor quadratics as we will build on these skills over the next few years. The better you are at factoring, the easier much of your remaining math studies will be and the way you get better at factoring is lots and lots of practice!

Solving Quadratics by Factoring

Since we know how to factor quadratics, we can now solve them. Solving quadratics by factoring takes very little effort after the factoring stage. This screencast will get you started.
