\[ \boxed { {x}^{2}{\frac {{\rm d}^{2}}{{\rm d}{x}^{2}}}y \left ( x \right ) -6\,y \left ( x \right ) =0} \]
Mathematica: cpu = 0.022503 (sec), leaf count = 18 \[ \left \{\left \{y(x)\to c_1 x^3+\frac {c_2}{x^2}\right \}\right \} \]
Maple: cpu = 0.0 (sec), leaf count = 15 \[ \left \{ y \left ( x \right ) ={\frac {{\it \_C1}}{{x}^{2}}}+{\it \_C2} \,{x}^{3} \right \} \]
