Factoring by Grouping
In this lesson, students will learn how to factor four-term polynomials by grouping. The instructor explains that whenever there are four terms, it is best to check if factoring by grouping is possible before trying to use the trinomial method. The instructor then walks through two examples and explains how to factor out common terms to arrive at the final answer. The lesson emphasizes the importance of grouping terms correctly and checking the factored expressions by multiplying them back together.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
