A) $8 ( 2 x + 1 ) ( x - 4 )$
B) $( 16 x - 8 ) ( x + 4 )$
C) $8 ( 2 x - 1 ) ( x + 4 )$
D) prime polynomial

Question

Quizplus · Accepted Answer

The trinomial can be factored by first factoring out the greatest common factor, which is 8, resulting in $8(2x^2 - 7x - 4)$. Then, factor the quadratic $2x^2 - 7x - 4$ into $(2x + 1)(x - 4)$. Thus, the complete factorization is $8(2x + 1)(x - 4)$.
