Expand (remove parentheses) and collect terms in decreasing powers of a:

(-8a^2+4a+2) = -8a^2+4a+2

-(8a+2) = -8a-2

Since the subtraction is implied in the negation of the secnd expression, you only have to **add** the two resulting expressions and regroup in decreasing powers of a.

Post your results if you need confirmation of the answer or additional help.
