Question

Find the zeros of the polynomial function.

f(x) = x^2 + 9x + 20

Answer 1

(x+4)(x+5)
x+4=0 x+5=0
x=-4 x=-5

I think this is the answer.

Answer 2

I would fill in the x's just to double check and make sure though.

Answer 3

ok, thanks.

Answer 4

Answer 5

i filled in the xs and got -9

Answer 6

Did you make sure that the terms you plugged in were negative? Sometimes calculators can be a little funky.

Answer 7

i think so

Answer 8

If those aren't the answers, I dunno what would be then. I'm pretty sure -5 and -4 are correct though.

Answer 9
