D( h )
h = 0
h = 0
h = 0
h in (-oo:0) U (0:+oo)
11/h-5 = 7/5-h // - 7/5-h
h+11/h-(7/5)-5 = 0
h+11/h-7/5-5 = 0
1*h^1+11*h^-1-32/5*h^0 = 0
(1*h^2-32/5*h^1+11*h^0)/(h^1) = 0 // * h^2
h^1*(1*h^2-32/5*h^1+11*h^0) = 0
h^1
h^2+(-32/5)*h+11 = 0
h^2+(-32/5)*h+11 = 0
DELTA = (-32/5)^2-(1*4*11)
DELTA = -76/25
DELTA < 0
h in { }
h belongs to the empty set
