Factor xy-7x+7y-49

$x y - 7 x + 7 y - 49$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(x y - 7 x) + 7 y - 49$

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

$x (y - 7) + 7 (y - 7)$

Step 2

Factor the polynomial by factoring out the greatest common factor, $y - 7$ .

$(y - 7) (x + 7)$
