Factor by Grouping 5x^3+4x^2+25x+20

$5 x^{3} + 4 x^{2} + 25 x + 20$

Step 1

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

$(5 x^{3} + 4 x^{2}) + 25 x + 20$

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

$x^{2} (5 x + 4) + 5 (5 x + 4)$

Step 2

Factor the polynomial by factoring out the greatest common factor, $5 x + 4$ .

$(5 x + 4) (x^{2} + 5)$
