Answer:
It's true
Explanation:
Operating the square we have:

Here we can factorize n:

The last line means our number (
) is divisible by n.
The clause of n>2 is true, but even its true for
because when n=1 the theorem means that the expression is divisible by 1, but this it's true for every integer, and for n=0 the expression will be 0 and 0 it´s divisible by 0 (Following the definition a|b if a=nb, with a, b and n integers).
