D( x )

x = 0

x = 0

x = 0

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

3*x+5/x-8 = 4/4 // - 4/4

3*x+5/x-(4/4)-8 = 0

3*x+5/x-8-1 = 0

3*x^1+5*x^-1-9*x^0 = 0

(3*x^2-9*x^1+5*x^0)/(x^1) = 0 // * x^2

x^1*(3*x^2-9*x^1+5*x^0) = 0

x^1

3*x^2-9*x+5 = 0

3*x^2-9*x+5 = 0

DELTA = (-9)^2-(3*4*5)

DELTA = 21

DELTA > 0

x = (21^(1/2)+9)/(2*3) or x = (9-21^(1/2))/(2*3)

x = (21^(1/2)+9)/6 or x = (9-21^(1/2))/6

x in { (9-21^(1/2))/6, (21^(1/2)+9)/6} 

x in { (9-21^(1/2))/6, (21^(1/2)+9)/6 }
