Factor 3y-12+xy-4x

$3 y - 12 + x y - 4 x$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(3 y - 12) + x y - 4 x$

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

$3 (y - 4) + x (y - 4)$

Step 2

Factor the polynomial by factoring out the greatest common factor, $y - 4$ .

$(y - 4) (3 + x)$
