A gardener is testing various values of x for a rectangular garden with length 2x + 5 meters and width x – 3 meters. The product gives the garden's area in square meters. Which polynomial can the gardener use in place of (2x + 5)(x – 3)?

This is one of those questions where there's a list of choices that goes along with it, but you're not sharing the list. The product of (2x + 5) and (x - 3) is (2x² - x - 15) . That may be useful.
