Factor 9rs+5cr+45(cs)+25c^2

$9 r s + 5 c r + 45 (c s) + 25 c^{2}$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(9 r s + 5 c r) + 45 (c s) + 25 c^{2}$

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

$r (9 s + 5 c) + 5 c (9 (s) + 5 c)$

Step 2

Factor the polynomial by factoring out the greatest common factor, $9 s + 5 c$ .

$(9 s + 5 c) (r + 5 c)$
