Question:New at maple - How to solve equations with RootOf / _Z?

Hi,

this forum has helped me a lot since I'm quite new at maple. There are lot of questions about the solution of _Z in roots but I still can't figure it out.

Here my problem:

f(x,y)= x*y - (V^(alpha)*W)/(V-a*x-b*y)^alpha

x>0, y>0, a>0, b>0, alpha>0, V>0, W>0, V-a*x-b*y>0

I need to find the maximum values for x and y. But all the solutions have got _Z.

How can I eliminate _Z? Thanks!

Best regards,

Won
