What constant must we place in the blank below in order to be able to factor the resulting expression into the product of two linear factors:

Question

2mn - 16m - 7n + ____

Answer 1

well, you have

2m(n-8) - 7n

So, if you want a common factor of n-8, you would need 56

That would give you

2m(n-8) - 7n + 56
= 2m(n-8) - 7(n-8)
= (2m-7)(n-8)

Answer 2

Read what I wrote. I guarantee that you will find the answer.
