9) Using the polynomial P(x) = x4 - 2x3 -4x - 3 evaluate P(3) both (a) directly and (b) using the remainder theorem. Show work for both parts for full credit (4 points) 9a) 9b) In problems 10 and 11, use the respective polynomial to answer the following: (a) use Descartes' rule of signs to determine the possible combination of positive and negative zeros; (b) use the rational zero theorem to determine the possible rational zeros of the polynomial; (c) test for and find all rational and compex zeros; and (d) factor as a product of linear factors (real and/or imaginary). 10)P(x) = x4+ 3x-3x- -7x +6 (10 points) 10a) possible positive rational zeros: 10a) possible negative rational zeros: 10b) list of possible rational zeros: 10c) rational zeros: 10d) factored form: P(x) =
