\begin{align*} y^{\prime }-6 y&=t^{6} {\mathrm e}^{6 t} \end{align*}

Solution by Maple

Time used: 0.002 (sec). Leaf size: 17

dsolve(diff(y(t),t)-6*y(t)=t^6*exp(6*t),y(t), singsol=all)
 
\[ y = \frac {\left (t^{7}+7 c_{1} \right ) {\mathrm e}^{6 t}}{7} \]

Solution by Mathematica

Time used: 0.052 (sec). Leaf size: 22

DSolve[D[y[t],t]-6*y[t]==t^6*Exp[6*t],y[t],t,IncludeSingularSolutions -> True]
 
\[ y(t)\to \frac {1}{7} e^{6 t} \left (t^7+7 c_1\right ) \]
