Quizplus · Accepted Answer

The given trinomial can be factored as a perfect square trinomial by identifying the square of the first term ($4x$)^2, the square of the last term ($7y$)^2, and twice the product of the first and last terms, which matches the middle term (-168xy). Thus, it factors into $3(4x - 7y)^2$.
