Solution by Maple

Time used: 0.014 (sec). Leaf size: 14

dsolve([x*diff(y(x),x$2)+2*diff(y(x),x)=6,y(1) = 4, D(y)(1) = 5],y(x), singsol=all)
 
\[ y = -\frac {2}{x}+3 x +3 \]

Solution by Mathematica

Time used: 0.011 (sec). Leaf size: 15

DSolve[{x*D[y[x],{x,2}]+2*D[y[x],x]==6,{y[1]==4,Derivative[1][y][1]==5}},y[x],x,IncludeSingularSolutions -> True]
 
\[ y(x)\to 3 x-\frac {2}{x}+3 \]
