Recall Euler's theorem: if
, then

where
is Euler's totient function.
We have
- in fact,
for any
since
and
share no common divisors - as well as
.
Now,

where the
are positive integer coefficients from the binomial expansion. By Euler's theorem,

so that

Plug in -2 to x in the formula
So f(-2)= ((-2)+1)^2
Your answer should be: 1
