Is it possible for a polynomial to contain ONLY and EXACTLY the following zeros?
4, -7+3i, -2+√13 , -2-√13, -4, 7 - 3i
No, because there is a set of imaginary zeros that are not a pair.
-7+3i would be paried with -7-3i
just as
7 - 3i would be paired with 7 + 3i
The irrational part of the quantity is the ONLY sign difference.
