dsolve(4*x^2*(1+x^2)*diff(y(x),x$2)+4*x*(1+6*x^2)*diff(y(x),x)-(1-25*x^2)*y(x)=0,y(x), singsol=all)
\[ y \left (x \right ) = \frac {c_{1} \sqrt {x}}{\left (x^{2}+1\right )^{\frac {3}{2}}}+\frac {c_{2} \left (\operatorname {arcsinh}\left (x \right ) x -\sqrt {x^{2}+1}\right )}{\sqrt {x}\, \left (x^{2}+1\right )^{\frac {3}{2}}} \]
