Solution for 20/x=x+1 equation: 


D( x )

x = 0

x = 0

x = 0

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

20/x = x+1 // - x+1

20/x-x-1 = 0

20*x^-1-1*x^1-1*x^0 = 0

(20*x^0-1*x^2-1*x^1)/(x^1) = 0 // * x^2

x^1*(20*x^0-1*x^2-1*x^1) = 0

x^1

20-x^2-x = 0

20-x^2-x = 0

DELTA = (-1)^2-(-1*4*20)

DELTA = 81

DELTA > 0

x = (81^(1/2)+1)/(-1*2) or x = (1-81^(1/2))/(-1*2)

x = -5 or x = 4

x in { -5, 4} 

x in { -5, 4 }
