cc Is wdF krxwn that, 3n the treginning of the 19th
century the mathematicians proved the impossibility
ing algebraieaJly polynomial equations of
gra?wr than four and as a result their attention
d on numerical methods. During this period
r conceived the idea to proceed in two steps;
that is, first to isolate the roots and then to approxi
mate them to any desired degree of accuracy. Ap
proximation is a rather trivial task and will not be
discussed in this paper; moreover, we will be mainly
concerned with the real roots.
Isolation of the real roots of a polynomial equa
tmn is the process of finding real, disjoint intervals
such that each contains exactly one real roqt and
every root is contained in some interval. In order to
