Finding Vertical Tangent lines
I need to find the vertical tangents for this function
$2y^3+y^3-y^5=x^4-2x^3+x^2$
I got this for the derivative
$dy/dx=(4X^3-6x^2+2x)/(6y^2+2y-5y^4)$
I know to set the denominator equal to zero and from there I'm stuck

$2y^3+y^3-y^5=x^4-2x^3+x^2$ check the exponents on the left side, please
