Solution for s+5/s=-6 equation: 


D( s )

s = 0

s = 0

s = 0

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

s+5/s = -6 // + 6

s+5/s+6 = 0

1*s^1+5*s^-1+6*s^0 = 0

(1*s^2+6*s^1+5*s^0)/(s^1) = 0 // * s^2

s^1*(1*s^2+6*s^1+5*s^0) = 0

s^1

s^2+6*s+5 = 0

s^2+6*s+5 = 0

DELTA = 6^2-(1*4*5)

DELTA = 16

DELTA > 0

s = (16^(1/2)-6)/(1*2) or s = (-16^(1/2)-6)/(1*2)

s = -1 or s = -5

s in { -5, -1} 

s in { -5, -1 }
