CAS Maple gives this as type [_separable]

\[ \boxed {y^{\prime }-2 t y^{2}-3 t^{2} y^{2}=0} \] With initial conditions \begin {align*} [y \left (1\right ) = -1] \end {align*}

Solution by Maple

Time used: 0.032 (sec). Leaf size: 16

dsolve([diff(y(t),t)=2*t*y(t)^2+3*t^2*y(t)^2,y(1) = -1],y(t), singsol=all)
 

\[ y \left (t \right ) = -\frac {1}{t^{3}+t^{2}-1} \]

Solution by Mathematica

Time used: 0.222 (sec). Leaf size: 17

DSolve[{y'[t]==2*t*y[t]^2+3*t^2*y[t]^2,{y[1]==-1}},y[t],t,IncludeSingularSolutions -> True]
 

\[ y(t)\to -\frac {1}{t^3+t^2-1} \]
