## __assassin__ 3 years ago quick quiz? will become fan&medal for best answer. Use the Rational Root Theorem to list all possible rational roots of the polynomial equation x^3 – x^2 – x – 3 = 0. Do not find the actual roots. -no roots - –3, –1, 1, 3 - 1, 3 - -33 A cubic polynomial with rational coefficients has the roots 6 + /{6} and 2/3 . Find one additional root. - –6 – /{6} - 6 + /{6} - –6 + /{6} /{?} = sq. rt. - 6 – /{6} What does Descartes's Rule of Signs tell you about the real roots of the polynomial? –2x^3 + 3x^2 – 5x – 2 = 0 -There is one

1. __assassin__

multiple choice for last one There is one positive root and either 2 or 0 negative roots. There are either 2 or 0 positive roots and there are either 2 or 0 negative roots. There is one positive root and one negative root. There are either 2 or 0 positive roots and one negative root.
