MaplePrimes Questions

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.

Hope you can assist me.

 

Thanks.

I came across a quite interesting problem as seen below  (and no it is not homework.)

I am just interested in how such a problem would be solved ?!
