1
Factor the polynomial $\left(a^2b-7b\right)$ by it's greatest common factor (GCF): $b$
$b\left(a^2-7\right)\left(a^2b+7b\right)$
2
Factor the polynomial $\left(a^2b+7b\right)$ by it's greatest common factor (GCF): $b$
$b^2\left(a^2-7\right)\left(a^2+7\right)$
Final Answer
$b^2\left(a^2-7\right)\left(a^2+7\right)$
