CAS Maple gives this as type [_linear]

\[ \boxed {y^{\prime }+\frac {y}{1+t}=t^{2}} \]

Solution by Maple

Time used: 0.0 (sec). Leaf size: 26

dsolve(diff(y(t),t)=-y(t)/(1+t)+t^2,y(t), singsol=all)
 

\[ y \left (t \right ) = \frac {3 t^{4}+4 t^{3}+12 c_{1}}{12 t +12} \]

Solution by Mathematica

Time used: 0.051 (sec). Leaf size: 28

DSolve[y'[t]==-y[t]/(1+t)+t^2,y[t],t,IncludeSingularSolutions -> True]
 

\[ y(t)\to \frac {3 t^4+4 t^3+12 c_1}{12 t+12} \]
