Solution for Y=-5/x2-5 equation: 


D( x )

x^2 = 0

x^2 = 0

x^2 = 0

1*x^2 = 0 // : 1

x^2 = 0

x = 0

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

Y = -5/(x^2)-5 // + -5/(x^2)-5

Y-(-5/(x^2))+5 = 0

Y+5*x^-2+5 = 0

5*x^-2 = -(Y+5) // : 5

x^-2 = (-(Y+5))/5

-2 < 0

1/(x^2) = (-(Y+5))/5 // * x^2

1 = x^2*((-(Y+5))/5) // : (-(Y+5))/5

-5*(Y+5)^-1 = x^2

x^2 = -5*(Y+5)^-1 // ^ 1/2

abs(x) = (-5)^(1/2)*(Y+5)^(-1/2)

x = (-5)^(1/2)*(Y+5)^(-1/2) or x = -((-5)^(1/2)*(Y+5)^(-1/2))

x in { (-5)^(1/2)*(Y+5)^(-1/2), -((-5)^(1/2)*(Y+5)^(-1/2)) }
