Correct. Therefore 2*sqrt(P1*P2)cos(180) is impossible as well as
ridiculous.


That's the interference term, Jim. Hecht, Born, and Wolf
all agree that the interference term can be negative.
Suggest you take a refresher course and alleviate the
ignorance you are displaying for everyone to observe.

Ah, but the ignorance being seen by all is all yours, sir. You
continue to ignore a significant detail, Cecil. See if you can find
it. Hint: people who write physics books know that power does not
interfere.

Please tell Hecht, Born, and Wolf that they are ridiculous.

I agree with them, and they don't post here. But if they did, they'd
be telling you the same thing as everyone else here.
