You can put this solution on YOUR website! if 0, 2, -2, 3, and 4-i are zeros of a polynomial with real coefficents, what is the smallest possible degree of the polynomial?
-----------
Since the coefficients are Real Numbers, 4+i must also be
a zero of the polynomial.
-----------
Therefore the lowest degree it could have is 6.
