Solution by Maple

Time used: 0.0 (sec). Leaf size: 37

dsolve(x^2*(1-2*x)*diff(y(x),x$2)-x*(5-4*x)*diff(y(x),x)+(9-4*x)*y(x)=0,y(x), singsol=all)
 

\[ y \left (x \right ) = \frac {c_{1} x^{3}}{\left (-1+2 x \right )^{2}}+\frac {c_{2} x^{3} \left (2 x -\ln \left (x \right )\right )}{\left (-1+2 x \right )^{2}} \]
