Question 956356: We are doing a chapter called "Factoring When Either Square Is A Square Of A Polynomial" and I'm having alot of trouble factoring this problem: a^2-(a+b)^2. I tried it like this: (a-a-b)(a+a+b) but it's still the wrong answer. They are telling me I'm missing one final step and I don't understand why. Please explain.

You can put this solution on YOUR website! We are doing a chapter called "Factoring When Either Square Is A Square Of A Polynomial" and I'm having alot of trouble factoring this problem: a^2-(a+b)^2. I tried it like this: (a-a-b)(a+a+b) but it's still the wrong answer. They are telling me I'm missing one final step and I don't understand why. Please explain.
===============
Combine like terms.
(a-a-b)(a+a+b) = -b*(2a + b)
