Factor by Grouping 2ab-6ac+3b-9c

$2 a b - 6 a c + 3 b - 9 c$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(2 a b - 6 a c) + 3 b - 9 c$

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

$2 a (b - 3 c) + 3 (b - 3 c)$

Step 2

Factor the polynomial by factoring out the greatest common factor, $b - 3 c$ .

$(b - 3 c) (2 a + 3)$
