\begin{align*} x^{2} y^{\prime \prime }+6 x y^{\prime }+4 y&=0 \end{align*}

Solution by Maple

Time used: 0.004 (sec). Leaf size: 15

dsolve(x^2*diff(y(x),x$2)+6*x*diff(y(x),x)+4*y(x)=0,y(x), singsol=all)
 
\[ y = \frac {c_{2} x^{3}+c_{1}}{x^{4}} \]

Solution by Mathematica

Time used: 0.012 (sec). Leaf size: 18

DSolve[x^2*D[y[x],{x,2}]+6*x*D[y[x],x]+4*y[x]==0,y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to \frac {c_2 x^3+c_1}{x^4} \]
