1. 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. -6. 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?

What does this mean

"Manu finds no sign changes in and 3 sign changes in."

Full question.
