You do not solve my mods, but I, nevertheless, will feed you with them over and over again until you are free while dealing with these freaky things.

The solutions are {-1, 2.42)

For G>0, the solution comes from solving G^2-2G-1=0
For G<0, the solution comes from solving G^2-1=0

You need to check also 0 < x < 1. x = 1 is a solution also.

x = {-1, 1, 1+sqrt(2)}
