Question: Classification of an ODE


check out this deq:


Maple says it's an Emden/Fowler deq with the following form:

Emden_Fowler_ode := x^p*p*(diff(y(x), x))/x+x^p*(diff(y(x), x, x))+x^sigma*y(x)^n = 0;

I tried to change the parameters p,n,sigma so that it describes my deq, but it does not completely fit.
I use n=1,p=0,sigma=-1 and i get


How do i get in the missing constant 2 ?


Maple solves it correctly by the way.
