Solution for z+8/z=-9 equation: 


D( z )

z = 0

z = 0

z = 0

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

z+8/z = -9 // + 9

z+8/z+9 = 0

1*z^1+8*z^-1+9*z^0 = 0

(1*z^2+9*z^1+8*z^0)/(z^1) = 0 // * z^2

z^1*(1*z^2+9*z^1+8*z^0) = 0

z^1

z^2+9*z+8 = 0

z^2+9*z+8 = 0

DELTA = 9^2-(1*4*8)

DELTA = 49

DELTA > 0

z = (49^(1/2)-9)/(1*2) or z = (-49^(1/2)-9)/(1*2)

z = -1 or z = -8

z in { -8, -1} 

z in { -8, -1 }
