Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, Beginning Algebra.
In this lesson, you will learn how to factor trinomials using a reverse-FOIL trial-and-error method. You will start by simplifying... the trinomial as much as possible, by removing any common factors or grouping any possible combinations. Then, try the reverse-FOIL by first breaking up the squared term. He also gives you a hint that when the last factor of the trinomial is negative, you know that the last terms of the binomials have to be opposites.[more]

This 2:53 long video explains that when a trinomial is factored, the result will always be in two parts The video is in lecture format and provides an example. The video may have to be stopped to check for student understanding.

Illustrates the steps for factoring a trinomial through writing on basic text slides. Many examples given. Although not very exciting, it would make a good tutorial for a student who is struggling with homework. Grades 8-12. 29:27 min.
