\[ \boxed {2 y t +y^{\prime }=2 t \,{\mathrm e}^{-t^{2}}} \]

Solution by Maple

Time used: 0.016 (sec). Leaf size: 16

dsolve(2*t*y(t)+diff(y(t),t) = 2*t/exp(t^2),y(t), singsol=all)
 

\[ y \left (t \right ) = \left (t^{2}+c_{1} \right ) {\mathrm e}^{-t^{2}} \]

Solution by Mathematica

Time used: 0.055 (sec). Leaf size: 19

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

\[ y(t)\to e^{-t^2} \left (t^2+c_1\right ) \]
