  1. Rational Zeros Theorem: The Rational Zeros Theorem states that if a polynomial has integer coefficients, then every rational zero, pq\frac{p}{q} (in lowest terms), has pp as a factor of the constant term and qq as a factor of the leading coefficient.\newlineFor the polynomial f(x)=x36x281f(x) = x^3 - 6x^2 - 81, the constant term is 81-81 and the leading coefficient is 11.
  2. Constant Term Factors: List all the factors of the constant term, 81-81. The factors of 81-81 are ±1\pm1, ±3\pm3, ±9\pm9, ±27\pm27, and ±81\pm81.
  3. Leading Coefficient Factors: List all the factors of the leading coefficient, 11. The factors of 11 are ±1\pm1.
  4. Potential Rational Zeros Calculation: According to the Rational Zeros Theorem, the potential rational zeros are the factors of the constant term divided by the factors of the leading coefficient. Since the leading coefficient is 11, the potential rational zeros are simply the factors of the constant term.
  5. Combine Factors for Zeros: Combine the factors of the constant term to list the potential rational zeros. The potential rational zeros are ±1\pm 1, ±3\pm 3, ±9\pm 9, ±27\pm 27, and ±81\pm 81.
