Exercise 63 Page 50

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 and the same exponent — can be combined. - 7h + 3h^2 - 4h - 3 In this case, we have two h-terms, one h^2-term, and one constant. Only the h-terms can be combined, so to simplify the expression we will rearrange it according to the Commutative Property of Addition and then combine like terms.

- 7h+3h^2-4h-3
