Solution for 2x-5/x=4 equation: 


D( x )

x = 0

x = 0

x = 0

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

2*x-(5/x) = 4 // - 4

2*x-(5/x)-4 = 0

2*x-5*x^-1-4 = 0

2*x^1-5*x^-1-4*x^0 = 0

(2*x^2-4*x^1-5*x^0)/(x^1) = 0 // * x^2

x^1*(2*x^2-4*x^1-5*x^0) = 0

x^1

2*x^2-4*x-5 = 0

2*x^2-4*x-5 = 0

DELTA = (-4)^2-(-5*2*4)

DELTA = 56

DELTA > 0

x = (56^(1/2)+4)/(2*2) or x = (4-56^(1/2))/(2*2)

x = (2*14^(1/2)+4)/4 or x = (4-2*14^(1/2))/4

x in { (4-2*14^(1/2))/4, (2*14^(1/2)+4)/4} 

x in { (4-2*14^(1/2))/4, (2*14^(1/2)+4)/4 }
