In general, finding the roots of a polynomial requires the use of an iterative method (e.g. Newton’s method or Bairstow’s method, as described below). This is not necessary for linear and quadratic equations, as we have seen above. It turns out that there is a non-iterative approach...
ON THE EXPECTED NUMBER OF REAL ROOTS OF A SYSTEM OF RANDOM POLYNOMIAL EQUATIONS We unify and generalize several known results about systems of random polynomials. We first classify all orthogonally invariant normal measures for spaces of polynomial mappings. For each such measure we calculate the ...

In this case, we show that the only restriction on the arrangement of the roots of such a polynomial together with the roots of its kth derivative comes from the standard Rolle''s theorem. On the other hand, we pose the general question of counting all possible root arrangements for a ...
