roots of a several variable for the equation $y-3x^2-y^3=0$
$begingroup$
How can I get the roots of the next equation?
$$y-3x^2-y^3=0$$
I just dont get the same answer than my teacher:
$$x = frac {- sqrt2}{3(3^{1/4})}, y = frac{-2}{sqrt3}$$

That equation has many roots

There had to be something else in the question. Maybe it was a system of two equations, not just this one equation by itself?

$x=0$, $y=0$, is just as valid.

Any point on the graph will satisfy the equation. You might wish to verify that your teacher's solution lies on the graph by squaring the $x$, cubing the $y$ and taking the designated combination.
