This lesson teaches you how to simplify polynomials using operations. You will learn how to distribute negative signs and combine like terms to simplify expressions. The transcript demonstrates how to simplify both a binomial and a trinomial and how to use the distributive property to multiply binomials and trinomials. You will also learn that you cannot combine terms with different exponents. By the end of the lesson, you will be able to simplify polynomials with ease.
Using operations to simplify polynomials
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.
