Solution for 2/b-1=b equation: 


D( b )

b = 0

b = 0

b = 0

b in (-oo:0) U (0:+oo)

2/b-1 = b // - b

2/b-b-1 = 0

2*b^-1-1*b^1-1*b^0 = 0

(2*b^0-1*b^2-1*b^1)/(b^1) = 0 // * b^2

b^1*(2*b^0-1*b^2-1*b^1) = 0

b^1

2-b^2-b = 0

2-b^2-b = 0

DELTA = (-1)^2-(-1*2*4)

DELTA = 9

DELTA > 0

b = (9^(1/2)+1)/(-1*2) or b = (1-9^(1/2))/(-1*2)

b = -2 or b = 1

b in { -2, 1} 

b in { -2, 1 }
