Solution by Maple

Time used: 0.002 (sec). Leaf size: 20

dsolve((a*x-b*x^2)*diff(y(x),x$2)+2*a*diff(y(x),x)+2*b*y(x)=0,y(x), singsol=all)
 
\[ y \left (x \right ) = \frac {c_{1} +\left (-b x +a \right )^{3} c_{2}}{x} \]

Solution by Mathematica

Time used: 0.047 (sec). Leaf size: 32

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