Factor jm+jn+km+kn

$j m + j n + k m + k n$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(j m + j n) + k m + k n$

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

$j (m + n) + k (m + n)$

Step 2

Factor the polynomial by factoring out the greatest common factor, $m + n$ .

$(m + n) (j + k)$
