CAS Maple gives this as type [_separable]

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

Solution by Maple

Time used: 0.015 (sec). Leaf size: 12

dsolve(3*t^2/y(t)-t^3/y(t)^2*diff(y(t),t)=0,y(t), singsol=all)
 

\[ y \left (t \right ) = -\frac {t^{3}}{c_{1}} \]

Solution by Mathematica

Time used: 0.04 (sec). Leaf size: 11

DSolve[3*t^2/y[t]-t^3/y[t]^2*y'[t]==0,y[t],t,IncludeSingularSolutions -> True]
 

\[ y(t)\to c_1 t^3 \]
