$x=0,2$

To find all the zeros of the function, set each factor to $0$ and solve for $x$ .

In your case:

$x^3=0$
$x=root(3)(0)$
$color(green)(x=0)$

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

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 $x=2$ .
