x-1 = 1/x
x^2 - x = 1
x^2 - x - 1 = 0
x = [ 1 +/- sqrt (1+4) ]/2
x = .5 +/- .5 sqrt 5
since it has to be positive
x = .5 + .5 sqrt 5
I'm having a hard time figuring out this question,
" There is only one positive number that satisfies the equation
(greek letter phe) - 1 = 1 / (greek letter phe)
Based on this definition, find the value of phe."
Thanks for the help I really appreciate it.
