\begin{align*} y^{\prime }+2 y&=20 \,{\mathrm e}^{3 x} \end{align*}

Solution by Maple

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

dsolve(diff(y(x),x)+2*y(x)=20*exp(3*x),y(x), singsol=all)
 
\[ y = \left (4 \,{\mathrm e}^{5 x}+c_{1} \right ) {\mathrm e}^{-2 x} \]

Solution by Mathematica

Time used: 0.055 (sec). Leaf size: 21

DSolve[D[y[x],x]+2*y[x]==20*Exp[3*x],y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to e^{-2 x} \left (4 e^{5 x}+c_1\right ) \]
