For quadrant two the points are always (-x,y) and x is always negative.
Image shows quadrant places.
so we know has roots equal to the cube roots of 1, not including
itself, which are
Any polynomial of the form is divisible by
if both
and
(this is the polynomial remainder theorem).
This means
But since is a root to
, it follows that
and since , we have
so that
From here, notice that if for some integer
, then
which is to say, is divisible by
for all
in the given range that are *not* multiples of 3, i.e. the integers
and
for
.
Since 2005 = 668*3 + 1, it follows that there are integers
such that
.
Finally, .
