Question

find the zeros of the function

f(x)=9x^3-45x^2+36x

Answer 1

0 = 9x^3 - 45x^2 + 36x...Step one. Now factor the equation

Answer 2

9x(x^2-5x+4)

Answer 3

Yes now we have (9x) (x^2-5x+4) = 0 Can we factor further?

Answer 4

(9x)(x-4)(x-5)

Answer 5

i meant (x-1)

Answer 6

(9x)(x-4)(x-1)

Answer 7

x cannot equal 0, 4, and 1?

Answer 8

Wow that is great work... But do not say it cannot equal x. When solving for zeros we want to know what values for x will give us a value of 0 for y.

Answer 9

thank you!
