Solution by Maple

Time used: 0.0 (sec). Leaf size: 20

dsolve(diff(y(t),t$2)-2*diff(y(t),t)+y(t)=t^2,y(t), singsol=all)
 

\[ y \left (t \right ) = \left (c_{1} t +c_{2} \right ) {\mathrm e}^{t}+t^{2}+4 t +6 \]

Solution by Mathematica

Time used: 0.014 (sec). Leaf size: 26

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