(a3+a2)-4a-4a-2
Factor out the greatest common factor (GCF) from each group.
a2(a+1)-4(a+1)a-2
a2(a+1)-4(a+1)a-2
Factor the polynomial by factoring out the greatest common factor, a+1.
(a+1)(a2-4)a-2
Rewrite 4 as 22.
(a+1)(a2-22)a-2
Since both terms are perfect squares, factor using the difference of squares formula, a2-b2=(a+b)(a-b) where a=a and b=2.
