comparison :

2n and 2 + n  =>       2 + n is greater when n < 2
                               2n is greater when n > 2


2n + 2 and 2(n + 2)  =>       2(n + 2) is always greater by 2 compared to 2n + 2


2n^2 and (2n)^2  =>       (2n)^2 is always greater


2n and n^2  =>     n^2 is always greater
