Factor xy+8x-y^2-8y

$x y + 8 x - y^{2} - 8 y$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(x y + 8 x) - y^{2} - 8 y$

Factor out the greatest common factor (GCF) from each group.

$x (y + 8) - y (y + 8)$

Step 2

Factor the polynomial by factoring out the greatest common factor, $y + 8$ .

$(y + 8) (x - y)$
