Solution for 1/x+3/x+2+6/8x+4 equation: 


D( x )

x = 0

x = 0

x = 0

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

(6/8)*x+1/x+3/x+2+4 = 0

3/4*x^1+4*x^-1+6*x^0 = 0

(3/4*x^2+6*x^1+4*x^0)/(x^1) = 0 // * x^2

x^1*(3/4*x^2+6*x^1+4*x^0) = 0

x^1

(3/4)*x^2+6*x+4 = 0

(3/4)*x^2+6*x+4 = 0

DELTA = 6^2-(4*4*(3/4))

DELTA = 24

DELTA > 0

x = (24^(1/2)-6)/(2*(3/4)) or x = (-24^(1/2)-6)/(2*(3/4))

x = 2/3*(2*6^(1/2)-6) or x = 2/3*(-2*6^(1/2)-6)

x in { 2/3*(-2*6^(1/2)-6), 2/3*(2*6^(1/2)-6)} 

x in { 2/3*(-2*6^(1/2)-6), 2/3*(2*6^(1/2)-6) }
