Exercise 20 Page 490

Remember, only like terms can be combined.

-8x^3

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. x^3- 9x^3 In this case we have only two x^3-terms, so let's combine like terms.
x^3-9x^3
-8x^3
