\begin{align*} \frac {3 t^{2}}{y}-\frac {t^{3} y^{\prime }}{y^{2}}&=0 \end{align*}

Solution by Maple

Time used: 0.004 (sec). Leaf size: 12

dsolve(3*t^2/y(t)-t^3/y(t)^2*diff(y(t),t)=0,y(t), singsol=all)
 
\[ y = -\frac {t^{3}}{c_{1}} \]

Solution by Mathematica

Time used: 0.038 (sec). Leaf size: 11

DSolve[3*t^2/y[t]-t^3/y[t]^2*D[y[t],t]==0,y[t],t,IncludeSingularSolutions -> True]
 
\[ y(t)\to c_1 t^3 \]
