Question

The product of two integers is w2 − 3w − 40, where w is a whole number. Write

Answer 1

To find the product of the two integers, the equation given has to be simplified. This simplified result would yield the correct answer. 

w^2 − 3w − 40 = w^2 - 8w + 5w - 40
                        = w(w - 8) + 5(w - 8)
                        = (w + 5)(w - 8)

I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
