Could you help me subtact this polynomials? (8a^2+4a+2)(8a+2)=

Expand (remove parentheses) and collect terms in decreasing powers of a:
(8a^2+4a+2) = 8a^2+4a+2
(8a+2) = 8a2
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.
