\[ \left \{ y \left ( x \right ) ={\frac {{\it \_C2}\,\ln \left ( x \right ) +{\it \_C1}}{x}} \right \} \] Mathematica raw input
DSolve[y[x] + 3*x*y'[x] + x^2*y''[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> (C[1] + C[2]*Log[x])/x}}
Maple raw input
dsolve(x^2*diff(diff(y(x),x),x)+3*x*diff(y(x),x)+y(x) = 0, y(x),'implicit')
Maple raw output
y(x) = (_C2*ln(x)+_C1)/x
