Answer 2

whats mainly confusing me is Part A:

Answer 3

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

Answer 4

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

Answer 5

then factor the inside :)

Answer 6

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

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10
