math is fucking awesome
Looks like we were all wrong...the answer was:
(s-1+8f)^2 (s-1-8f)^2

that answer is fucking wrong
it should be
(s - 1 + 8f)(s - 1 - 8f)

if you multiply out what i just wrote you WILL get s^2 - 2s + 1 - 64f^2

(s - 1 - 8f)(s - 1 + 8f)
= s(s - 1 + 8f) - 1(s - 1 + 8f) - 8f(s - 1 + 8f)
= s^2 - s + 8fs - s + 1 - 8f - 8fs - 8f - 64f^2
= s^2 - 2s + 1 - 64f^2
yep i was totally right

Hold on...I think my boyfriend is just typing it all in wrong...starting to piss me off. Another problem asked for w^3 - 125 factored, and I gave him (w-5)^2(w+5) and it said it was wrong...because it didn't want that simplified of an answer.
FUCKING starting to piss me off.

so w^3 - 125 = w^3 - 5^3 = (w - 5)(w^2 + 5w + 25) which can't be factorised any further

No, Carmen. No. (a+b)(a-b)!=a+b(a-b)!=a^2-b^2 != means not equal.
Permious has been correct on everything I've read.
