For Exercises 47-54, use the remainder theorem to determine if the given number e is a zero of the polynomial. (See Example 7) 47. f(x) = x* + 3r' - 7 + 13x – 10o b. c = -5 48. g(x) = 2r + 13x' - 10x - 19x + 14 %3D а. с 2 a. c= -2 b.c = -7 50. g(x) = 3x + - 30x – 10 b. c = -V10 52. n(x) = x + 4x + 9x + 36 b. c = -3i 54. f(x) = 2x - 5x + 54x – 26 b. c = 1- 5i 49. p(x) = 2r + 3x - 22r - 33 b. c = -VIT a. c = -2 a. c = -3 51. m(x) = x - 2 + 25x – 50 b. c = -5i 53. g(x) = x - 11 + 25x + 37 b. c = 6 -i a. c = 5i a. c= 31 a. c = 6+i a. c =1+ 5i

(6x2+12x-15) / (x+8) Use synthetic division to divide the polynomials

8. Is the expression 16 - 6x18 a polynomial. If it is not, what rules it out? yes no if no, what rules it out?_ 9. Is the expression x-'(x– 4) – x²(1 – x³) a polynomial. If not, what rules it out? yes no if no, what rules it out?
