Resumen:
We provide explicit formulae for the coefficients of the order-d polynomial subresultant of (x-a)^m and (x-b)^n with respect to the set of Bernstein polynomials {(x-a)^j (x-b)^(d-j), j=0,...,d}. They are given by hypergeometric expressions arising from determinants of binomial Hankel matrices.
