Step 1.1

Group the first two terms and the last two terms.

$(21 x y + 15 x) + 35 r y + 25 r$

Step 1.2

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

$3 x (7 y + 5) + 5 r (7 y + 5)$

Step 2

Factor the polynomial by factoring out the greatest common factor, $7 y + 5$ .

$(7 y + 5) (3 x + 5 r)$
