Answer
GCF=$3g$
$3b(b^{3}-3b+2)$
Work Step by Step
Find the GCF of the terms of each polynomial. Then factor the polynomial.
$3b^{4}-9b^{2}+6b$
All of the terms have a $b$ so the GCF must contain a $b$
All of the coefficients are divisible by $3$ so the GCF must contain a $3$
GCF=$3g$
Factor:
$3b(b^{3}-3b+2)$
