Use the Rational Roots Theorem to Write the Function in Factored

question 32

Multiple Choice

Use the rational roots theorem to write the function in factored form and find all zeroes. Note a = 1. p(x) = x⁴ + 6x³ - 13x² - 66x + 72

• A) p(x) = (x - 1)(x - 3)(x + 4)(x + 6); zeroes: 1, 3, -4, -6
• B) p(x) = (x + 1)(x + 3)(x - 4)(x - 6); zeroes: -1, -3, 4, 6
• C) p(x) = (x - 1)(x + 3)(x - 4)(x + 6); zeroes: 1, -3, 4, -6
• D) p(x) = (x + 1)(x - 3)(x + 4)(x - 6); zeroes: -1, 3, -4, 6
