Step 2.1

Group the first two terms and the last two terms.

$(b c + 4 a c) - 7 b d - 28 a d$

Step 2.2

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

$c (b + 4 a) - 7 d (b + 4 a)$

Step 3

Factor the polynomial by factoring out the greatest common factor, $b + 4 a$ .

$(b + 4 a) (c - 7 d)$
