Solution for (m-2/m+2)(m/m-1) equation: 


D( m )

m = 0

m = 0

m = 0

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

(m-(2/m)+2)*(m/m-1) = 0

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

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

m-2*m^-1+2 = 0

1*m^1-2*m^-1+2*m^0 = 0

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

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

m^1

m^2+2*m-2 = 0

m^2+2*m-2 = 0

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

DELTA = 12

DELTA > 0

m = (12^(1/2)-2)/(1*2) or m = (-12^(1/2)-2)/(1*2)

m = (2*3^(1/2)-2)/2 or m = (-2*3^(1/2)-2)/2

m in { (-2*3^(1/2)-2)/2, (2*3^(1/2)-2)/2} 

(m-((-2*3^(1/2)-2)/2))*(m-((2*3^(1/2)-2)/2)) = 0

0*(m-((-2*3^(1/2)-2)/2))*(m-((2*3^(1/2)-2)/2)) = 0

( m-((-2*3^(1/2)-2)/2) )

m-((-2*3^(1/2)-2)/2) = 0 // + (-2*3^(1/2)-2)/2

m = (-2*3^(1/2)-2)/2

( m-((2*3^(1/2)-2)/2) )

m-((2*3^(1/2)-2)/2) = 0 // + (2*3^(1/2)-2)/2

m = (2*3^(1/2)-2)/2

m in { (-2*3^(1/2)-2)/2, (2*3^(1/2)-2)/2 }
