\begin{align*} y^{\prime \prime }+16 y^{\prime }&=t \end{align*}

Solution by Maple

Time used: 0.002 (sec). Leaf size: 21

dsolve(diff(y(t),t$2)+16*diff(y(t),t)=t,y(t), singsol=all)
 
\[ y = \frac {t^{2}}{32}-\frac {{\mathrm e}^{-16 t} c_{1}}{16}-\frac {t}{256}+c_{2} \]

Solution by Mathematica

Time used: 4.794 (sec). Leaf size: 42

DSolve[D[y[t],{t,2}]+16*D[y[t],t]==t,y[t],t,IncludeSingularSolutions -> True]
 
\[ y(t)\to \int _1^te^{-16 K[2]} \left (c_1+\int _1^{K[2]}e^{16 K[1]} K[1]dK[1]\right )dK[2]+c_2 \]
