Solution for 7x-14/x-2 equation: 


D( x )

x = 0

x = 0

x = 0

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

7*x-(14/x)-2 = 0

7*x-14*x^-1-2 = 0

7*x^1-14*x^-1-2*x^0 = 0

(7*x^2-2*x^1-14*x^0)/(x^1) = 0 // * x^2

x^1*(7*x^2-2*x^1-14*x^0) = 0

x^1

7*x^2-2*x-14 = 0

7*x^2-2*x-14 = 0

DELTA = (-2)^2-(-14*4*7)

DELTA = 396

DELTA > 0

x = (396^(1/2)+2)/(2*7) or x = (2-396^(1/2))/(2*7)

x = (6*11^(1/2)+2)/14 or x = (2-6*11^(1/2))/14

x in { (2-6*11^(1/2))/14, (6*11^(1/2)+2)/14} 

x in { (2-6*11^(1/2))/14, (6*11^(1/2)+2)/14 }
