rule is given by

Halley’s rule:
…
►For moderate or large values of
it is not uncommon for the magnitude of the
right-
hand side of (
3.8.14) to be very large compared with unity, signifying that the computation of zeros of polynomials is often an ill-posed problem.

cross the negative real axis or pass through the origin.

principal values; compare §
