\[\left [y \left (x \right ) = \frac {\textit {\_C1} \sinh \left (x \right )}{x^{2}}+\frac {\textit {\_C2} \cosh \left (x \right )}{x^{2}}\right ]\] Mathematica raw input
DSolve[(2 - x^2)*y[x] + 4*x*y'[x] + x^2*y''[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> ((2*C[1])/E^x + E^x*C[2])/(2*x^2)}}
Maple raw input
dsolve(x^2*diff(diff(y(x),x),x)+4*x*diff(y(x),x)+(-x^2+2)*y(x) = 0, y(x))
Maple raw output
[y(x) = _C1*sinh(x)/x^2+_C2*cosh(x)/x^2]
