Solve 1/x = x - 1 What is special about the positive solution?

Basile [38]

1 = x^2 - x
x^2-x-1=0
quadratic formula:
$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} = \frac{-1 \pm \sqrt{1^2 - 4(1)(-1)}}{2} = \frac{-1 \pm \sqrt5}{2}$
the positive root is special because it's equal to the golden ratio

Step-by-step explanation:

Proportions

It's given three duos (D) is worth as two trios (T), i.e.:

3D = 2T

Steve has 36 trios, that is, 36T. To find the equivalence to duos, we multiply the given relationship by 18:

18*3D = 18*2T

Operating:

54D = 36T

Therefore, 36 trios are equivalent to 54 duos.
