Answer 1

Okayy @Argos

Answer 2

factor out x

Answer 3

x(x^2 -9x + 20)

Answer 4

either x is 0 or (x^2 -9x +20) is 0

so use quadtratic on x2 -9x +20

Answer 5

Okayy i did what you said and got 0,4,5 which i believe woud be the zeros @argos

Answer 6

Since the original function is to the 3rd power there will be 3 zeros
