DSolve[-((2 - x^2)*y[x]) + x^3*y'[x] + x^2*y''[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> (2*C[1] - (2*x*C[2])/E^(x^2/2) + Sqrt[2*Pi]*C[2]*Erf[x/Sqrt[2]])/(2*x)
}}
Maple raw input
dsolve(x^2*diff(diff(y(x),x),x)+x^3*diff(y(x),x)-(-x^2+2)*y(x) = 0, y(x))
Maple raw output
[y(x) = 1/x*_C1+_C2/x*(Pi^(1/2)*2^(1/2)*erf(1/2*2^(1/2)*x)-2*x*exp(-1/2*x^2))]
