Question 26486: A Polynomial of Degree at Most the Taylor Order Has Zero Remainder

Original question and givens

Coefficients=[12, 6] are in ascending power order, with exact rationals and trailing zero coefficients removed for degree. Center=0, point=1/2, order=1; keep terms through that order, and define remainder=f(x)−Taylor_value. Give (degree, order, Taylor_terms, remainder, zero_remainder, certificate).
