We are not worthy ... we are not worthy ... (assembled masses bowing down)
But it seems like cheating to include 1 and z

Re: Proof Help
I did all that, but with p-2, p and p+2 for better cancellation.
I got it to 4(3p²+2) and then gave up because I forgot about the 1 and z bit, so I didn't post it.
Why did the vector cross the road?
It wanted to be normal.
