Factor completely using the grouping method to factor trinomials. If unfactorable, indicate that the polynomial is prime.
-$$2 x ^ { 2 } + 23 x + 11$$
A) $( 2 x + 1 ) ( x + 11 )$
B) prime
C) $( 2 x + 11 ) ( x + 1 )$
D) $( 2 x - 1 ) ( x - 11 )$

Question

Quizplus · Accepted Answer

The factors of 22 are 1 and 22, and the factors of 11 are 1 and 11. The only pair of factors that add up to 23 is 1 and 22, so the factors of $2 x ^ { 2 } + 23 x + 11$ are $2 x + 1$ and $x + 11$.
