Factor the polynomial completely. If the polynomial cannot be factored, write "prime."
-$y ^ { 2 } - 2 y - 80$
A)(y + 10)(y - 8)
B)(y - 80)(y + 1)
C)(y - 10)(y + 8)
D)Prime

Question

Quizplus · Accepted Answer

The correct factorization is found by looking for two numbers that multiply to -80 and add to -2. Those numbers are -10 and +8, making the factorization (y - 10)(y + 8).
