Answer 1

(a-b)^2=(a-b)(a+b)

therefore plug in those and use the foil method.

\]

Answer 4

@wio That is wrong.

Answer 5

@asapbleh : Wio is correct.

Answer 6

Really?

Answer 7

@Dido525 @wio is wrong. Just try expanding (a-b)(a-b) and see if youll get (a-b)^2 if you think Im wrong.

Answer 8

He didn't expand it though.

Answer 9

You are right in the fact you will get a^2-2ab+b^2

Answer 10

@Dido525 Please look at the original question.

Answer 11

But it's not wrong what he did.

Answer 12

\[
(a-b)(a+b)=a^2-b^2 \neq (a-b)^2
\]
