Example 14:

        So far we have looked at many complex roots, this

        example shows how they can be related to locations

        in the argand diagram. The plot of the function
                   2
            = 4   + 3   + 2 is shown below.




















        It  is  quite  clear  the  roots  are  complex;  show  the
        function reflected about the minimum.
