Answer

$8(v+3)(v-2)$.

Work Step by Step

The given polynomial is $=8v^2+8v-48$ Factor out $8$. $=8(v^2+v-6)$ Rewrite $v$ as $3v-2v$. $=8(v^2+3v-2v-6)$ Group the terms. $=8[(v^2+3v)+(-2v-6)]$ Factor each group. $=8[v(v+3)-2(v+3)]$ Factor out $(v+3)$. $=8(v+3)(v-2)$ Hence, the factor of the polynomial is $8(v+3)(v-2)$.
