If the polynomial function P(x ) = ant? + an_1xn-1+...+ ajx+ ap has integer coefficients, then the only numbers that could possibly be rational zeros of P are all of the form -, where p is a factor of the constant coefficient a0 x and q is a factor of the leading coefficient an The possible rational zeros of P(x) = 21x3 + 3x2 - 22x - 39 are (Enter your answers as a comma-separated list.)
