Solution for x-2=35/x equation: 


D( x )

x = 0

x = 0

x = 0

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

x-2 = 35/x // - 35/x

x-(35/x)-2 = 0

x-35*x^-1-2 = 0

1*x^1-35*x^-1-2*x^0 = 0

(1*x^2-2*x^1-35*x^0)/(x^1) = 0 // * x^2

x^1*(1*x^2-2*x^1-35*x^0) = 0

x^1

x^2-2*x-35 = 0

x^2-2*x-35 = 0

DELTA = (-2)^2-(-35*1*4)

DELTA = 144

DELTA > 0

x = (144^(1/2)+2)/(1*2) or x = (2-144^(1/2))/(1*2)

x = 7 or x = -5

x in { -5, 7} 

x in { -5, 7 }
