In this lesson, the instructor demonstrates how to factor polynomials completely by factoring out the greatest common factor and then factoring the resulting quadratic trinomials. The instructor provides several examples of different degrees of difficulty and shows different methods for factoring. The key takeaway is to always check for the greatest common factor and to keep factoring until each factor can't be factored any further.
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.
