A

Explanation

To find the other factor when 9x² + 6xy + 4y² is a factor of 27x³ - 8y³, we can use polynomial division.Let's perform the division:            3x - 2y        ___________________9x² + 6xy + 4y² | 27x³ + 0x² - 8y³            - (27x³ + 18xy² + 12y³)        ___________________                      -18xy² - 20y³The remainder of the division is -18xy² - 20y³.Therefore, the other factor is 3x - 2y.
