dsolve((2*x*diff(y(x),x)-y(x))^2=8*x^3,y(x), singsol=all)
\begin{align*} y \left (x \right ) = \left (-\sqrt {2}\, x +c_{1} \right ) \sqrt {x} y \left (x \right ) = \left (\sqrt {2}\, x +c_{1} \right ) \sqrt {x} \end{align*}

DSolve[(2*x*y'[x]-y[x])^2==8*x^3,y[x],x,IncludeSingularSolutions -> True]
\begin{align*} y(x)\to \sqrt {x} \left (-\sqrt {2} x+c_1\right ) y(x)\to \sqrt {x} \left (\sqrt {2} x+c_1\right ) \end{align*}
