In this lesson, you will learn how to subtract two trinomials by distributing the subtraction sign to all the terms and then combining like terms. The key is to remember that you are subtracting the entire trinomial, not just one term. By following these steps, you can easily subtract two trinomials and get a trinomial as a result.
Subtracting two trinomials
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.
