Final answer:
The expression x²y - 2xy - 24y can be factored by removing the common factor of y, resulting in a trinomial that is not a perfect square.
Step-by-step explanation:
The expression x²y - 2xy - 24y can be factored by first factoring out a common factor of y. After removing the common factor of y, the remaining factor is a trinomial that is not a perfect square.
