**Question:** Which of the following are zeros of the function P(x) = 4x^4 + 8x^3 - 7x^2 - 21x - 9? **Options:** 1. \(\frac{1 \pm \sqrt{7}}{2}\) 2. \(\frac{1 \pm \sqrt{5}}{2}\) 3. \(\frac{1 \pm \sqrt{3}}{2}\) 4. \(\frac{3}{2}\) **Explanation:** This question requires finding the roots of the polynomial function P(x). The zeros represent the x-values at which the function equals zero. Each given option is a potential zero of the function. To solve, substitute each option into the polynomial and verify if they satisfy the equation P(x) = 0.
