Question

Select the factors of xy − 4x + 2y − 8.

(x − 2)(y + 4)

(x + 2)(y − 4)

(x − 4)(y + 2)

(x + 4)(y − 2)
Do I FOIL this? @Mertsj

Answer 1

FOIL your options and see which one is like the first one

Answer 2

It is (x + 2)(y − 4)

Answer 3

Okay. Will do.

Answer 4

Oh. Can you show me how you got that? @aga3t

Answer 5

Because (x)(y) = xy
(x)(-4)= -4x
(2)(y)= +2y
(2)(-4)= -8

Answer 6

You just FOIL it

Answer 7

Thanks @aga3t !
