result_type AlgebraicKernel_d_1::Isolate_1::operator()	(	first_argument_type	a,
		second_argument_type	p
	)

Computes an open isolating interval \( I=(l,u)\) for \( a\) with respect to the real roots of \( p\).

It is not required that \( a\) is a root of \( p\).

Postcondition

\( a \in I\).

\( p(x) \neq0 | \forall x \in\overline{I}\backslash a\).
