\begin{align*} y^{\prime }-3 y&=12 \,{\mathrm e}^{2 x} \end{align*}

Solution by Maple

Time used: 0.000 (sec). Leaf size: 15

dsolve(diff(y(x),x)-3*y(x)=12*exp(2*x),y(x), singsol=all)
 
\[ y = \left ({\mathrm e}^{x} c_{1} -12\right ) {\mathrm e}^{2 x} \]

Solution by Mathematica

Time used: 0.044 (sec). Leaf size: 19

DSolve[D[y[x],x]-3*y[x]==12*Exp[2*x],y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to e^{2 x} \left (-12+c_1 e^x\right ) \]
