Factor the polynomial completely. If the polynomial cannot be factored, write "prime."
-$y ^ { 2 } - 6 y - 55$
A) $( y - 11 ) ( y + 5 )$
B) $( y + 11 ) ( y - 5 )$
C) prime
D) $( \mathrm { y } - 55 ) ( \mathrm { y } + 1 )$

Question

Quizplus · Accepted Answer

The correct factorization is found by looking for two numbers that multiply to -55 and add to -6. Those numbers are -11 and 5, so the polynomial factors to $(y - 11)(y + 5)$.
