Answer
$(x-2)(x^2+5)$
Work Step by Step
Regroup the terms to obtain:
$=(x^3-2x^2)+(5x-10)$
Factor out the greatest common factor of each group to obtain:
$=x^2(x-2) + 5(x-2)$
The $GCF$ for the two terms is a binomial, $(x-2)$. Even though it is a binomial, we can factor it out just like we would factor out a number or a variable. Thus, we factor out the binomial to obtain:
$=(x-2)(x^2+5)$
