Question

What are the zeros of the polynomial function f(x) = x3 − 9x2 + 20x

0, −5, 4

0, 5, 4

0, 5, −4

0, −5, −4

Answer 1

the answer is 0,5,4 trust mee

Answer 2

First you take out x since every variable has it.
x(x^2-9x+20)
Then you break it up to find out what makes 20 when multiplied but -9 when added.
x(x-5)(x-4)
So the 0s would be 0,5,4
