0, –5, 4

0, 5, –4

0, 5, 4

Answer 1

it's the first answer

Answer 2

I think it 0 -4 and -5

Answer 3

first you factor out the x so that the problem is now x(x^2+9x+20)

Answer 4

then you factor again so that you have x(x+4)(x+5)=0

Answer 5

and you finally set each one to zero so your answers are 0, -4, and -5

Answer 6

kewl thx
