Lesson Description:

This video demonstrates how to factor some polynomials completely by factoring out the GCF first. In these problems, after factoring out the GCF, you will get a quadratic trinomial that can be factored.

    This lesson helps you learn the idea that you must factor out a common factor or GCF from every term of a polynomial first before attempting to factor it. Sometimes, this common factor can be just a number or a variable, or sometimes it can be a polynomial expression itself. Be sure to check out this lesson if you are having trouble factoring polynomials. The final problem is especially challenging and fun!
