If a polynomial has a zero then the polynomial has a factor of the form:
(x - z)
where "z" is the zero.
Your polynomial, with zeros of 2, 2i and -2i, will have factor of:
(x - 2)(x - 2i)(x - (-2i))
The third factor simplifies to:
(x - 2)(x - 2i)(x + 2i)
All you have to do now is multiply. I suggest that you start by multiplying the last two factors first. (Hint: the i's will disappear!)
