14. Let f(x) =6x3 -19x2 +2x+35 a) Use the Rational Roots Theorem to find all possible rational roots of f (x) =0. 2 b) Factor f(x) over Z, given that one factor is of the form x + a, and two are of the form bx + c, where where a, b, c E Z. You are required to exclusively apply the Factor Theorem using your results from "a."
