Factor.
-$$x ^ { 3 } - x ^ { 2 } - 72 x$$
A) $x ( x + 8 ) ( x - 9 )$
B) Prime
C) $\left( x ^ { 2 } + 1 \right) ( x - 72 )$
D) $x ( x + 9 ) ( x - 8 )$

Question

Quizplus · Accepted Answer

First, factor out the greatest common factor, which is $x$, to get $x(x^2 - x - 72)$. Then, factor the quadratic equation $x^2 - x - 72$ to get $(x + 8)(x - 9)$. So, the complete factorization is $x(x + 8)(x - 9)$.
