dont think you can just add Ns and numbers. its a product of a 3 numbers, not a sum. we are essentially treating it (A) as N+N+1+N-4.

Sorry all, we are not allowed to reproduce OG questions here, so I have deleted the question. However, let me say that the BEST way to do this one, by far, is to test numbers. Since n must be greater than 6, plug n is 7 and eliminate. Then plug 8 and eliminate. At that point you've got it!
