3-83.

Find the dimensions of the generic rectangle at right. Then write an equivalency statement (length · width = area) of the area as a product and as a sum. Homework Help ✎

 $x^2$ $-5x$ $3x$ $-15$

First, find the dimensions of the rectangle.

(x + 3) and (x − 5)

Area = (Length)(Width)

(x + 3)(x − 5) = x2 − 2x − 15
