How do I isolate X in this equation?

Asked by PhiNotPi (12681points) August 20th, 2011

What are the steps to isolating X in the equation-
1 = x + x^2
By isolate I mean to make it so that there is only one X by itself, not two.
The anwser for X is 0.618… as determined by my calculator, but I want to know how to get that number.

This is NOT homework.
