Solution for (h^2-2h-2)/h equation: 


D( h )

h = 0

h = 0

h = 0

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

(h^2-(2*h)-2)/h = 0

(h^2-2*h-2)/h = 0

h^2-2*h-2 = 0

h^2-2*h-2 = 0

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

DELTA = 12

DELTA > 0

h = (12^(1/2)+2)/(1*2) or h = (2-12^(1/2))/(1*2)

h = (2*3^(1/2)+2)/2 or h = (2-2*3^(1/2))/2

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

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

( h-((2*3^(1/2)+2)/2) )

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

h = (2*3^(1/2)+2)/2

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

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

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

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