D( x )

x = 0

x = 0

x = 0

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

(2/7)*x+11/x = 10/9 // - 10/9

(2/7)*x+11/x-(10/9) = 0

(2/7)*x+11/x-10/9 = 0

2/7*x^1+11*x^-1-10/9*x^0 = 0

(2/7*x^2-10/9*x^1+11*x^0)/(x^1) = 0 // * x^2

x^1*(2/7*x^2-10/9*x^1+11*x^0) = 0

x^1

(2/7)*x^2+(-10/9)*x+11 = 0

(2/7)*x^2+(-10/9)*x+11 = 0

DELTA = (-10/9)^2-(4*11*(2/7))

DELTA = -6428/567
