\begin{align*} {y^{\prime }}^{3}-4 x y y^{\prime }+8 y^{2}&=0 \end{align*}

✓ Solution by Maple

Time used: 0.128 (sec). Leaf size: 29

dsolve(diff(y(x),x)^3-4*x*y(x)*diff(y(x),x)+8*y(x)^2=0,y(x), singsol=all)
 

\begin{align*} y &= \frac {4 x^{3}}{27} \\ y &= 0 \\ y &= \frac {\left (4 c_{1} x -1\right )^{2}}{64 c_{1}^{3}} \\ \end{align*}
