Factor completely. If the polynomial cannot be factored, write ʺprime.ʺ
-$$2 x ^ { 2 } - 12 x + 10$$
A) $2 ( x - 1 ) ( x - 10 )$
B) $2 ( x + 5 ) ( x + 1 )$
C) $2 ( x - 5 ) ( x - 1 )$
D) $( 2 x - 1 ) ( x - 10 )$

First, factor out the greatest common factor, which is 2, to get $2(x^2 - 6x + 5)$. Then, find factors of 5 that add up to -6, which are -5 and -1, leading to $2(x - 5)(x - 1)$.
