prove that u(z+zw)={+1,-1,+w,-w,+w^2,-w^2}

 

[Prove It]

prove that u(z+zw)={+1,-1,+w,-w,+w^2,-w^2}

You may as well ask us to prove that if the sky is green then faeces smell like roses...

prove that u(z+zw)={+1,-1,+w,-w,+w^2,-w^2}

Seriously, there must be more to this problem. What are you told about "u"?
