Using long division to find the first term, by which we can get the initial (or
final) value and its position
(a) unstable, final value = -1 at position 0
(b) stable, initial value = 1 at position 1
(c) stable, final value = 1 at position 0
(d) stable, none
(e) unstable, initial value = 1 at position 0
(f) unstable, final value = 1 at position -1
