Solution for 2m/(m^2+15m+54) equation: 


D( m )

m^2+15*m+54 = 0

m^2+15*m+54 = 0

m^2+15*m+54 = 0

m^2+15*m+54 = 0

DELTA = 15^2-(1*4*54)

DELTA = 9

DELTA > 0

m = (9^(1/2)-15)/(1*2) or m = (-9^(1/2)-15)/(1*2)

m = -6 or m = -9

m in (-oo:-9) U (-9:-6) U (-6:+oo)

(2*m)/(m^2+15*m+54) = 0

m^2+15*m+54 = 0

m^2+15*m+54 = 0

DELTA = 15^2-(1*4*54)

DELTA = 9

DELTA > 0

m = (9^(1/2)-15)/(1*2) or m = (-9^(1/2)-15)/(1*2)

m = -6 or m = -9

(m+9)*(m+6) = 0

(2*m)/((m+9)*(m+6)) = 0

2*m = 0 // : 2

m = 0

m = 0
