Simplifying
(5a)(-2a2b2)
Remove parenthesis around (5a)
5a(-2a2b2)
Remove parenthesis around (-2a2b2)
5a * -2a2b2
Reorder the terms for easier multiplication:
5 * -2a * a2b2
Multiply 5 * -2
-10a * a2b2
Multiply a * a2b2
-10a3b2

Wouldn't simplifying give a(5-2ab^2) ?
I think what you tried is expansion... been awhile. Nah nevermind that's all wrong! Someone up there got it right!

You have to MULTIPLY. Where do your + and - come from?
