Factor the trinomial completely. If the polynomial cannot be factored, write "prime."
-$x ^ { 2 } + x - 56$
A) prime
B) $( x - 7 ) ( x + 8 )$
C) $( x + 1 ) ( x - 56 )$
D) $( x - 8 ) ( x + 7 )$

Question

Quizplus · Accepted Answer

The trinomial $x^2 + x - 56$ can be factored as $(x - 7)(x + 8)$ because the product of -7 and 8 is -56 and their sum is 1.

Factor the Trinomial Completely x2+x−56x ^ { 2 } + x - 56x2+x−56
