Question 264821
when the reciprocal of a real number is subtracted from 1, the difference is equal to the number. find the number.
---------
Let the number be "x":
Equation:
1 - (1/x) = x
Multiply thru by x:
x - 1 = x^2
Rearrange:
x^2-x+1 = 0
---
x = [1 +- sqrt(1 -4*1*1)]/2
---
x = [1 +- sqrt(-3)}/2
----
Note: x is NOT a Real number.
