Final answer:
The value of ac is -16. The value of b is 0. The factored form of 16x² - 1 is (4x - 1)(4x + 1).
Step-by-step explanation:
The polynomial is 16x² - 1. To find the value of ac, we can use the formula ac = a * c. In this case, a = 16 and c = -1, so ac = 16 * -1 = -16.
The value of b is the coefficient of the x term, which is 0 in this case.
To find two numbers that multiply to get ac and add to get b, we need to factor the polynomial. The factored form of 16x² - 1 is (4x - 1)(4x + 1).
