Solution for m-9/m+1=-5 equation: 


D( m )

m = 0

m = 0

m = 0

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

m-(9/m)+1 = -5 // + 5

m-(9/m)+1+5 = 0

m-9*m^-1+1+5 = 0

1*m^1-9*m^-1+6*m^0 = 0

(1*m^2+6*m^1-9*m^0)/(m^1) = 0 // * m^2

m^1*(1*m^2+6*m^1-9*m^0) = 0

m^1

m^2+6*m-9 = 0

m^2+6*m-9 = 0

DELTA = 6^2-(-9*1*4)

DELTA = 72

DELTA > 0

m = (72^(1/2)-6)/(1*2) or m = (-72^(1/2)-6)/(1*2)

m = (6*2^(1/2)-6)/2 or m = (-6*2^(1/2)-6)/2

m in { (-6*2^(1/2)-6)/2, (6*2^(1/2)-6)/2} 

m in { (-6*2^(1/2)-6)/2, (6*2^(1/2)-6)/2 }
