Solution for 11/2x-3/x equation: 


D( x )

x = 0

x = 0

x = 0

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

(11/2)*x-(3/x) = 0

(11/2)*x-3*x^-1 = 0

11/2*x^1-3*x^-1 = 0

(11/2*x^2-3*x^0)/(x^1) = 0 // * x^2

x^1*(11/2*x^2-3*x^0) = 0

x^1

(11/2)*x^2-3 = 0

(11/2)*x^2-3 = 0

DELTA = 0^2-(-3*4*(11/2))

DELTA = 66

DELTA > 0

x = (66^(1/2)+0)/(2*(11/2)) or x = (0-66^(1/2))/(2*(11/2))

x = (66^(1/2))/11 or x = (-66^(1/2))/11

x in { (-66^(1/2))/11, (66^(1/2))/11} 

x in { (-66^(1/2))/11, (66^(1/2))/11 }
