Prove that if 4 is subtracted from the square of an interger greater than 3, the result is a composite number.
I need to prove it deductively.
I know that an example could be written as:
(n+4)^2-4 = composite number
it is n+4 as the number has to be greater than 3 so if I can prove 4 first then i think i should be able to prove the rest.... let me know if i am on the right track.
