Rational Zeros of Functions

Question

List all possible rational zeros for the function. (Enter your answers as a comma-separated list.)

f(x) = 2x³ + 3x² − 6x + 3

Answer 1

P={ +-1, +-3}

Q={ +-1. +-2}

P/Q = {+-1, +-1/2. +-3 . +- 3/2}

You may have to input the answer as 1, -1, 1/2, -1/2, 3, -3, 3/2, -3/2

incidentally 1/2 is the only rational root
