Factor wv-9v+wk-9k

$w v - 9 v + w k - 9 k$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(w v - 9 v) + w k - 9 k$

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

$v (w - 9) + k (w - 9)$

Step 2

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

$(w - 9) (v + k)$
