Exercise 22 Page 490

Remember, only like terms can be combined.

5x^2

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. 7x^2- 2x^2 In this case we have only two x^2-terms, so let's combine like terms.

7x^2-2x^2
