Using indirect proof, show that if n^2 + 6n+16 is odd then n is odd.

n^2 +6n + 16 is odd, then

n^2 + 6n is odd, then

Continue ...

Using indirect proof, show that if n^2 + 6n+16 is odd then n is odd.

One form of indirect proof is by contradiction.

Suppose that n is not odd (that is, n is even, so it can be written as 2k). What can you conclude?

n^2 +6n + 16 is odd, then

n^2 + 6n is odd, then

I can't be more direct, but your outline is for a direct proof.
