Factor 4x+16+xy+4y

$4 x + 16 + x y + 4 y$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(4 x + 16) + x y + 4 y$

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

$4 (x + 4) + y (x + 4)$

Step 2

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

$(x + 4) (4 + y)$
