Find the polynomial function with real coefficients that has the given zeroes: 6 and -2i. Express the function in general form.
--------------------------------------------------------
Since the coefficients are Real Numbers, and since -2i is a zero,
2i must also be a zero.
-------------------
f(x) = (x-6)(x-2i)(x+2i)
f(x) = (x-6)(x^2+4)
