List all possible rational zeros given by the Rational Zeros Theorem (but don't check to see which actually are zeros) (Enter your answers as a comma-separated list.) P(x) = x3 − 2x2 + 5 10/15/2013 | Jeremy from Kemp, TX | 1 Answer | 0 Votes Mark favorite Subscribe Comment
P/Q where p = 5 or p = -5 and q = 1 or q = -1 5/1, 5/-1, -5/1, -5/-1 So 5 and -5 are the possible rational zeros. Neither appear to work since 5^3 -2(5^2) + 5 = 80 and (-5)^3 - 2 (-5)^2 + 5 = -125 - 50 + 5 = -170. 10/16/2013 | Jason S. Comment
