Solution by Maple

Time used: 0.0 (sec). Leaf size: 9

dsolve([(1+y(t)/t^2)-1/t*diff(y(t),t)=0,y(2) = 1],y(t), singsol=all)
 

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

Solution by Mathematica

Time used: 0.027 (sec). Leaf size: 14

DSolve[{(1+y[t]/t^2)-1/t*y'[t]==0,{y[2]==1}},y[t],t,IncludeSingularSolutions -> True]
 

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