Factor fg-5g+4f-20

$f g - 5 g + 4 f - 20$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(f g - 5 g) + 4 f - 20$

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

$g (f - 5) + 4 (f - 5)$

Step 2

Factor the polynomial by factoring out the greatest common factor, $f - 5$ .

$(f - 5) (g + 4)$
