A) $2 ( 8 x - 7 ) ^ { 2 }$
B) prime
C) $2 ( 8 x + 7 ) ^ { 2 }$
D) $2 ( 8 x - 7 ) ( 8 x + 7 )$

Question

Quizplus · Accepted Answer

The polynomial can be factored by first factoring out the greatest common divisor, which is 2, resulting in $2(64x^2 - 112x + 49)$. Recognizing the trinomial as a perfect square, it further factors into $2(8x - 7)^2$.
