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.
( 8h^3 + 3h)+( 4h^3 + 5h)
In this case, we have two h^3-terms and two h-terms.
Only the h^3-terms and h-terms can be combined, so to simplify the expression we will remove the parentheses, rearrange it according to the Commutative Property of Addition, and then combine like terms.
