whats mainly confusing me is Part A:

jigglypuff314 · Answer

factor out a y^2   what do you get? :)

anonymous · Answer

y^2(3x^2-2x-8)

jigglypuff314 · Answer

then factor the inside :)

anonymous · Answer

(sorry internet sucks)     (3x^2-x)(-2x-8)

jigglypuff314 · Answer

3x^2-2x-8
I think would be  (3x+4)(x-2)

anonymous · Answer

Oh, how would you get that i have been doing it wrong i guess

jigglypuff314 · Answer

thinking of the factors of 3 and 8
1 3 2 4
and what combination of adding/subtracting would get me  -2
4 minus (3 times 2) = -2

anonymous · Answer

Oh okay

anonymous · Answer

just got a revelation of the entire module xD

anonymous · Answer

for B it would be 5 and 5 to get 10 and 25

anonymous · Answer

@jigglypuff314 so for c how would that be done and D is there isn't a common factor right?
