go form and find all zeroes. Note a = 1. 41. f(x) = x - 13x + 12 Use the rational zero theorem to write each polynomial in factored form and find all zeroes. 42. 8(x) = x - 21x + 20 43. h(x) = x - 19x - 30 44 . H(x) = x' - 28x - 48 45. p(x) = x - 2x2 - 11x + 12 46. 9(x) = x3 - 4x2 - 7x + 10 47 . Y1 = X - 6x2 - x + 30 48. Y2 = x - 4x2 - 20x + 48 49. Y3 = x4 - 15x2 + 10x + 24 50. YA = x - 23x2 - 18x + 40
