roots of a several variable for the equation $y-3x^2-y^3=0$












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.

Graph of the function in question



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.
