Solution by Maple

Time used: 0.0 (sec). Leaf size: 45

dsolve(x*diff(diff(y(x),x),x)-(2*a*x^2+1)*diff(y(x),x)+b*x^3*y(x)=0,y(x), singsol=all)
 

\[ y \left (x \right ) = c_{1} {\mathrm e}^{\frac {x^{2} \left (\sqrt {a^{2}-b}+a \right )}{2}}+c_{2} {\mathrm e}^{\frac {x^{2} \left (-\sqrt {a^{2}-b}+a \right )}{2}} \]
