Factor 18xy-4x-9y+2

$18 x y - 4 x - 9 y + 2$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(18 x y - 4 x) - 9 y + 2$

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

$2 x (9 y - 2) - (9 y - 2)$

Step 2

Factor the polynomial by factoring out the greatest common factor, $9 y - 2$ .

$(9 y - 2) (2 x - 1)$
