Final answer:

The expression 912 - 64y² is a difference of squares and its correct factored form is (30.4 + 8y)(30.4 - 8y), which is not listed in any of the provided options, indicating a possible typo.

Step-by-step explanation:

The factored form of the expression 912 - 64y² is sought. This expression is a difference of squares, which can be factored using the formula a² - b² = (a + b)(a - b). In this case, 912 is the square of 30.4, and 64y² is the square of 8y, so the factored form of 912 - 64y² is (30.4 + 8y)(30.4 - 8y), which does not match any of the provided options A) to D). Therefore, there must be a typo in the question or the answer choices.
