3(x + 7) = 9(x - 1)
3(x) + 3(7) = 9(x) - 9(1)
3x + 21 = 9x - 9
<u>- 3x - 3x </u>
21 = 3x - 9
<u>+ 9 + 9</u>
<u>30</u> = <u>3x</u>
3 3
10 = x
You can factor this out by thinking of the factors of 56 that have a sum of -1. 7 and 8 are factors of 56 and to get a sum of -1, 8 should be negative. 7 + -8 = -1
So

factored out is (y+7x)(y-8x)
We can check this using FOIL
F = (y)(y) =

O = (y)(-8x) = -8xy
I = (7x)(y) = 7xy
L = (7x)(-8x) =

(7) (11) =
