\[[y \left (x \right ) = \textit {\_C1} \BesselJ \left (p , x\right )+\textit {\_C2} \BesselY \left (p , x\right )]\] Mathematica raw input
DSolve[-((p^2 - x^2)*y[x]) + x*y'[x] + x^2*y''[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> BesselJ[p, x]*C[1] + BesselY[p, x]*C[2]}}
Maple raw input
dsolve(x^2*diff(diff(y(x),x),x)+x*diff(y(x),x)-(p^2-x^2)*y(x) = 0, y(x))
Maple raw output
[y(x) = _C1*BesselJ(p,x)+_C2*BesselY(p,x)]
