Solution for x-12=4/x equation: 


D( x )

x = 0

x = 0

x = 0

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

x-12 = 4/x // - 4/x

x-(4/x)-12 = 0

x-4*x^-1-12 = 0

1*x^1-4*x^-1-12*x^0 = 0

(1*x^2-12*x^1-4*x^0)/(x^1) = 0 // * x^2

x^1*(1*x^2-12*x^1-4*x^0) = 0

x^1

x^2-12*x-4 = 0

x^2-12*x-4 = 0

DELTA = (-12)^2-(-4*1*4)

DELTA = 160

DELTA > 0

x = (160^(1/2)+12)/(1*2) or x = (12-160^(1/2))/(1*2)

x = (4*10^(1/2)+12)/2 or x = (12-4*10^(1/2))/2

x in { (12-4*10^(1/2))/2, (4*10^(1/2)+12)/2} 

x in { (12-4*10^(1/2))/2, (4*10^(1/2)+12)/2 }
