D( h )
h = 0
h = 0
h = 0
h in (-oo:0) U (0:+oo)
8*h-(6/h) = 0
8*h-6*h^-1 = 0
8*h^1-6*h^-1 = 0
(8*h^2-6*h^0)/(h^1) = 0 // * h^2
h^1*(8*h^2-6*h^0) = 0
h^1
8*h^2-6 = 0
8*h^2-6 = 0
DELTA = 0^2-(-6*4*8)
DELTA = 192
DELTA > 0
h = (192^(1/2)+0)/(2*8) or h = (0-192^(1/2))/(2*8)
h = (3^(1/2))/2 or h = (-3^(1/2))/2
h in { (-3^(1/2))/2, (3^(1/2))/2}
h in { (-3^(1/2))/2, (3^(1/2))/2 }
