x=0,2x=0,2

Explanation:

To find all the zeros of the function, set each factor to 00 and solve for xx.

In your case:

x^3=0x3=0
x=root(3)(0)x=30
color(green)(x=0)x=0

x-2=0x2=0
color(green)(x=2)x=2

You can see this holds true graphically as well:

graph{x^3(x-2)^2 [-5, 5, -2.5, 2.5]}

:., the zeros of the function are x=0 and x=2.
