D( x )
x = 0
x = 0
x = 0
x in (-oo:0) U (0:+oo)
2/x-x+2/6-6 = 0
2*x^-1-1*x^1-17/3*x^0 = 0
(2*x^0-1*x^2-17/3*x^1)/(x^1) = 0 // * x^2
x^1*(2*x^0-1*x^2-17/3*x^1) = 0
x^1
(-17/3)*x-x^2+2 = 0
(-17/3)*x-x^2+2 = 0
DELTA = (-17/3)^2-(-1*2*4)
DELTA = 361/9
DELTA > 0
x = ((361/9)^(1/2)-(-17/3))/(-1*2) or x = (-(-17/3)-(361/9)^(1/2))/(-1*2)
x = -6 or x = 1/3
x in { -6, 1/3}
x in { -6, 1/3 }
