The set C of all complex numbers under the operations of addition and multiplication as defined above satisfies following properties: ... where w stands for an imaginary cube roots of unity. If z 1 +wz 2 +w2z 3 =0, then (z 1-z 2)=-w2(z 3-z 2); hence z 1 - z 2 = w 2 z 2 - z 3 = z 2 - z 3 . similarly other part.
