Solution by Maple

Time used: 0.0 (sec). Leaf size: 30

dsolve(4*x^2*diff(y(x),x$2)+ y(x) = 8*sqrt(x)*(1+ln(x)),y(x), singsol=all)
 

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

DSolve[4*x^2*y''[x]+y[x] == 8*Sqrt[x]*(1+Log[x]),y[x],x,IncludeSingularSolutions -> True]
 

\[ y(x)\to \frac {1}{6} \sqrt {x} \left (2 \log ^3(x)+6 \log ^2(x)+3 c_2 \log (x)+6 c_1\right ) \]
