Lesson Summary:

In this lesson, you will learn how to factor non-basic trinomials into 2 binomials using various methods, including factoring out the greatest common factor first. The lesson also covers how to factor trinomials when the coefficient of the squared variable is negative. One important reminder throughout the lesson is to always check your answer to make sure it multiplies out to the original problem, and that you cannot factor it any further.

Lesson Description:

This is part 7 of factoring non-basic trinomials into 2 binomials. More practice factoring trinomials using various methods. Also covers factoring trinomials when the coefficient of the squared variable is negative, and factoring completely by factoring out the greatest common factor first.
