\[ \boxed { 4\,{x}^{2}{\frac {{\rm d}^{2}}{{\rm d}{x}^{2}}}y \left ( x \right ) +y \left ( x \right ) =0} \]
Mathematica: cpu = 0.010501 (sec), leaf count = 27 \[ \left \{\left \{y(x)\to c_1 \sqrt {x}+\frac {1}{2} c_2 \sqrt {x} \log (x)\right \}\right \} \]
Maple: cpu = 0.0 (sec), leaf count = 17 \[ \left \{ y \left ( x \right ) ={\it \_C1}\,\sqrt {x}+{\it \_C2}\,\sqrt { x}\ln \left ( x \right ) \right \} \]
