dsolve(x*diff(y(x),x)^4-2*y(x)*diff(y(x),x)^3+12*x^3 = 0,y(x), singsol=all)
\begin{align*} y \left (x \right ) = -\frac {2 \sqrt {-6 x}\, x}{3} \\ y \left (x \right ) = \frac {2 \sqrt {-6 x}\, x}{3} \\ y \left (x \right ) = -\frac {2 \sqrt {6}\, x^{\frac {3}{2}}}{3} \\ y \left (x \right ) = \frac {2 \sqrt {6}\, x^{\frac {3}{2}}}{3} \\ y \left (x \right ) = 6 c_{1}^{3}+\frac {x^{2}}{2 c_{1}} \\ \end{align*}
