Multiple Choice

Factor completely. If the polynomial cannot be factored, write ʺprime.ʺ
- $$24 x ^ { 6 } + 66 x ^ { 4 } + 45 x ^ { 2 }$$

A) $3 x ^ { 2 } \left( 2 x ^ { 2 } - 3 \right) \left( 4 x ^ { 2 } - 5 \right)$
B) $3 x ^ { 2 } \left( 4 x ^ { 2 } + 5 \right) \left( 2 x ^ { 2 } + 3 \right)$
C) $3 \left( 4 x ^ { 4 } + 5 \right) \left( 2 x ^ { 2 } + 3 \right)$
D) $\left( 12 x ^ { 3 } + 15 \right) \left( 2 x ^ { 3 } + 3 \right)$
