Question: RootOf

I have the following solution with Maple 13:  RootOf((-4+4d)_Z+(4-4d)_Z-3d+2).

I understand that to obtain an explicit solution to the complex roots, I have to use evalf.

So when I write evalf(%) or evalf(RootOf((-4+4d)_Z+(4-4d)_Z-3d+2)), Maple returns the same complex root.

 

Hope you can assist me.

 

Thanks.
