first, I want to make clear the question, you want to know what different between them or want to time them together? I mean (x+4)(x-4)* (x+4)(x+4)?

Find the two products below. Compare and contrast, in complete sentences, the similarities and differences of the two.

(x + 4)(x − 4) and (x + 4)(x + 4)
