DSolve[(1 - 4*p^2 + 4*k*x - x^2)*y[x] + 4*x^2*y''[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> C[1]*WhittakerM[k, p, x] + C[2]*WhittakerW[k, p, x]}}
Maple raw input
dsolve(4*x^2*diff(diff(y(x),x),x)+(4*k*x-4*p^2-x^2+1)*y(x) = 0, y(x),'implicit')
Maple raw output
y(x) = _C1*WhittakerM(k,p,x)+_C2*WhittakerW(k,p,x)
