- You have to expand it first :
(Note : by expand I mean multiply the term outside the brackets by everything inside)
x^2 + x = 1
- Subtract 1 from both sides :
x^2 + x - 1 = 0
- Use the quadratic equation to get answers of:
x = [tex]\frac{-1+\sqrt{5} }{2}[/tex] , x = [tex]\frac{-1-\sqrt{5} }{2}[/tex]
