Is x = -1 a Valid Solution for the Equation x/1 = x + 1/x?

AI Thread Summary
The discussion revolves around solving the equation x/1 = x + 1/x. Participants analyze the equation, questioning its interpretation as either x/1 = x + 1/x or x/1 = (x + 1)/x. The latter leads to the quadratic equation x^2 - x - 1 = 0, which has solutions that include the golden ratio, approximately 1.618. There is debate over whether x = 1 or x = -1 are valid solutions, with consensus that x = 1 is a solution, while x = -1 is not valid. The conversation touches on concepts of limits and anomalies, with some suggesting that setting x to infinity could satisfy the equation. Overall, the discussion highlights the complexities and nuances of solving these algebraic expressions.

0/0 . . or
SqrRoot of -0
 
My answer is "hedons"
 
x/1 = x
so your eq becomes:

x = x - 1/x
->0=-1/x...
unless you take the limit you are nobody...

x=±sqrt(1/(1-1))

you're the 4 grade student, who just studied what an "equation" is

Is that written as \frac {x}{1} = x + \frac{1}{x} or is it supposed to be \frac {x}{1} = \frac{x+1}{x}?
 
oh yea, cause if its the second one then its the golden ratio. 1.61828 or whatever.

then if it's the second

x^2 = x+1
x^2-x-1 =0
x=(1(+-) (((-1)^2)-(4)(1)(-1))^0.5) (2(1))^-1
x= (1(+-)(5^0.5))/2
interesting ?
 
An anomoly, that's what you are!

i think it should be infinity. putting value of xas infinite we will satisfy the equation.

Are we ever getting a answer here? :confused:

x = 1/x has no solution. For x = 1 + 1/x, x = ~1.618 (the "golden ratio").

?! I think x=1 is a solution.
 
  • #14
So is x = -1.

I believe he meant to say 0=1/x.

Ahhhh...x = 1 is so obvious. but x = -1 doesn't work.
