Work Step by Step

$6q^{4}=2.3.q.q.q.q$ and $3q^{3}=3.q.q.q$ Hence, $GCF=$$3.q.q.q=3q^{3}$ $24q^{2}=$ and $12q=2.2.3.q$ Hence, $GCF=$$2.2.3.q=12q$ After grouping : $=(6q^{4}+3q^{3})-(24q^{2}+12q)$ $=3q^{3}(2q+1)-12q(2q+1)$ $=(3q^{3}-12q)(2q+1)$ $=(3q)(q^{2}-4)(2q+1)$ $=3q(q+2)(q-2)(2q+1)$ (Since $(a^{2}-b^{2})$$=(a+b)(a-b))$
