Yes. The indefinite integral is a set of functions differing only by an 
additive constant. The variables x and y in this context are dummy 
variables, mere place holders.

Ask yourself this are the identities:

(x + a)^2 = x^2 + 2*a*x + a^2

(y + a)^2 = y^2 + 2*a*y + a^2

the same identity. The answer is yes.

The variables are just place holders.
