Factor kq-9q+kr-9r

$k q - 9 q + k r - 9 r$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(k q - 9 q) + k r - 9 r$

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

$q (k - 9) + r (k - 9)$

Step 2

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

$(k - 9) (q + r)$
