Unit 3 Lesson 2 Part 1 Adding and Subtracting Polynomials

Suppose we are given the following problem: First, we need to identify our like terms.

Next, we need to combine our like terms Next, we need to combine our like terms. Remember the rules involving signed numbers.

Let’s try another example... This time, we have to distribute the subtraction symbol to each number in the parenthesis behind the sign.

Again, we need to identify and combine like terms.

Summary…. Now go watch the videos  When adding: Identify like terms and combine Remember the rules of adding signed numbers! Now go watch the videos  When subtracting: Distribute subtract into the parenthesis Identify like terms and combine Remember the rules of adding signed numbers!
