    To get the product of (3a + 2) and (4a² - 2a + 9), we can apply the rules of distribution over multiplication and have 3a (4a² - 2a + 9) + 2 (4a² - 2a + 9) 12a³ - 6a² + 27a + 8a² - 4a + 18 Adding like terms of the same degree, we can simplify it into 12a³ + 2a² + 23a + 18 Therefore, the answer is D.
