Manu determines the roots of a polynomial equation by applying the theorems he knows. he organizes the results of these theorems. from the fundamental theorem of algebra, manu knows there are 3 roots to the equation. from descartes’ rule of sign, manu finds no sign changes in and 3 sign changes in . the rational root theorem yields as the list of possible rational roots. the lower bound of the polynomial is . the upper bound of the polynomial is 1. what values in manu’s list of rational roots should he try in synthetic division in light of these findings?
