A) $x ^ { 2 } ( 5 x - 15 ) ( x - 7 )$
B) $5 x ^ { 2 } \left( x ^ { 2 } - 10 x + 21 \right)$
C) $x ^ { 2 } ( x - 3 ) ( 5 x - 35 )$
D) $5 x ^ { 2 } ( x - 3 ) ( x - 7$

Question

Quizplus · Accepted Answer

The expression can be factored by first taking out the greatest common factor, $5x^2$, resulting in $5x^2(x^2 - 10x + 21)$. The quadratic $x^2 - 10x + 21$ can be factored further into $(x - 3)(x - 7)$.
