\[ \boxed {y^{\prime }-\frac {4 y^{2} x^{3}-3 x^{2} y}{x^{3}-2 y x^{4}}=0} \]

Solution by Maple

Time used: 0.078 (sec). Leaf size: 41

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

\begin{align*} y \left (x \right ) &= \frac {x -\sqrt {x^{2}+4 c_{1}}}{2 x^{2}} \\ y \left (x \right ) &= \frac {x +\sqrt {x^{2}+4 c_{1}}}{2 x^{2}} \\ \end{align*}

Solution by Mathematica

DSolve[y'[x]==(4*x^3*y[x]^2-3*x^2*y[x])/(x^3-2*x^4*y[x]),y[x],x,IncludeSingularSolutions -> True]
 

\begin{align*} y(x)\to \frac {x^3-\sqrt {x^2} \sqrt {x^4+4 c_1 x^2}}{2 x^4} \\ y(x)\to \frac {x^3+\sqrt {x^2} \sqrt {x^4+4 c_1 x^2}}{2 x^4} \\ \end{align*}
