\begin{align*} y^{\prime \prime }-12 y^{\prime }+36 y&=0 \end{align*}

Solution by Maple

Time used: 0.003 (sec). Leaf size: 14

dsolve(diff(y(x),x$2)-12*diff(y(x),x)+36*y(x)=0,y(x), singsol=all)
 
\[ y = {\mathrm e}^{6 x} \left (c_{2} x +c_{1} \right ) \]

Solution by Mathematica

Time used: 0.014 (sec). Leaf size: 18

DSolve[D[y[x],{x,2}]-12*D[y[x],x]+36*y[x]==0,y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to e^{6 x} (c_2 x+c_1) \]
