#### Answer

$2x^{6}+2x^{5}+2x^{4}+2x^{3}$
(sample answer)

#### Work Step by Step

Reversing the steps for finding the gcf, let's say we found it to be
GCF = $2x^{3}$
The four terms can be generated by multiplying the gcf with $x^{3},x^{2}x,$ and 1:
$2x^{3}\cdot x^{3}+2x^{3}\cdot x^{2}+2x^{3}\cdot x+2x^{3}\cdot 1 =$
= $2x^{6}+2x^{5}+2x^{4}+2x^{3}$
