This answer is correct because I simplified using like terms.

Step-by-step explanation:

Subtracting Polynomials

They key to subtract, multiply, add, and divide polynomials is by using like terms. Like terms are values with the same bases. For example :

              and        are like terms because they have the base  

Step 1: Move like terms together

First, let's remove all parenthesis:

Now let's move all like terms together:

Step 2: Simplify

Now we can add and subtract the like terms like we do in any other problem

Step 3: Explaining your answer

Just say: "This answer is correct because I simplified using like terms"
