dsolve(x^2*(1+x^2)*diff(y(x),x$2)-x*(1-4*x^2)*diff(y(x),x)+(1+2*x^2)*y(x)=0,y(x), singsol=all)
\[ y \left (x \right ) = \frac {c_{1} x}{\left (x^{2}+1\right )^{\frac {3}{2}}}+\frac {c_{2} x \left (\sqrt {x^{2}+1}-\operatorname {arctanh}\left (\frac {1}{\sqrt {x^{2}+1}}\right )\right )}{\left (x^{2}+1\right )^{\frac {3}{2}}} \]
