Solution by Maple

Time used: 0.015 (sec). Leaf size: 18

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

Solution by Mathematica

Time used: 0.038 (sec). Leaf size: 19

DSolve[{(2*t*y[t]+3*t^2)+(t^2-1)*D[y[t],t]==0,{y[0]==1}},y[t],t,IncludeSingularSolutions -> True]
 
\[ y(t)\to \frac {-t^2+t-1}{t-1} \]
