Factor completely. If the polynomial cannot be factored, write ʺprime.ʺ
-$$x ^ { 2 } + 8 x - 20$$
A) $( x - 10 ) ( x + 2 )$
B) $( x - 10 ) ( x + 1 )$
C) $( x + 10 ) ( x - 2 )$
D) Prime

Question

Quizplus · Accepted Answer

The polynomial $x^2 + 8x - 20$ can be factored as $(x + 10)(x - 2)$ because the product of 10 and -2 is -20, and their sum is 8.
