Exercise 18 Page 490

Remember, only like terms can be combined.

9w^2x

Practice makes perfect

The first step in simplifying this expression is to identify which, if any, terms can be combined. Remember, only like terms — constant terms or terms with the same variable — can be combined. 8w^2x+ w^2x In this case, we have only two w^2x-terms, so let's combine like terms.

8w^2x+w^2x

Add terms

9w^2x
