Hi,
a) you mean Equal[] instead of Set[]
Maximize[{g + (1 - g)*x - (g/2)*x^2 - (g/2)*v,
x == (a/c) + sqrt ((d/c)*(v - 1/c))}, x]
b) that is nonsense because you have one equation
for x, you can insert this into your objective
function and you get a constant with respect to
x. So there is nothing to minimize
Regards
Jens
