Use your fx calculator to factorise the cubic part of this

        polynomial, (w5)







        Now select 4,







        Enter the coefficients,
                 2=3=z11=z6=



                 =                       =                      =






                             th
        The factorised 4  order nominator is,
                     (2   − 1)(   + 3)(   − 2)(2   + 1)


        Now find  the factors of  the denominator (page 35)
        using your fx calculator,

                                3
                                           2
                             3   + 11   + 5   − 3
