Factoring a Trinomial by Taking Out Common Terms
In this lesson, the focus is on factoring a trinomial by taking out common terms. The first step is always to factor out what the terms have in common, which in this case is x squared and 2. This leaves us with a trinomial, which we can then factor by looking at the coefficient of the terms. By finding two numbers that multiply to give the constant term and add to give the coefficient of the linear term, we can factor the trinomial. Combining these steps allows us to quickly and easily factor trinomials by taking out common terms first.

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.
