Solution for z+5/z-6=9/-4 equation: 


D( z )

z = 0

z = 0

z = 0

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

z+5/z-6 = 9/(-4) // - 9/(-4)

z+5/z-(9/(-4))-6 = 0

z+5/z+9/4-6 = 0

1*z^1+5*z^-1-15/4*z^0 = 0

(1*z^2-15/4*z^1+5*z^0)/(z^1) = 0 // * z^2

z^1*(1*z^2-15/4*z^1+5*z^0) = 0

z^1

z^2+(-15/4)*z+5 = 0

z^2+(-15/4)*z+5 = 0

DELTA = (-15/4)^2-(1*4*5)

DELTA = -95/16

DELTA < 0
