Question 978660: Find a polynomial function of lowest degree with rational coefficients that has the given numbers as some of its zeros.
-4i, 2

This will have degree 3.
Complex roots occur in pairs, 4i and minus 4i
x^2+16=0 would be one pair of roots
x-2=0 would be the other.
x^3-2x^2+16x-32
=x^3+14x^2-32
