  1. Couldn't you explain this just one more time? Source

  2. David couldn’t have the money. It is not possible that David has the money. Source

How can the first one be a request? Please show me some examples of these two sentences.

In many societies, it is considered more polite and respectful to say some things indirectly. The first sentence you quoted is an example of that. If you said something like

Hey, you, explain it again!

it would be considered quite direct and quite blunt, maybe even impolite or rude.

To be more polite, you can state your request indirectly. You don't spell out the request, but you ask why the other person can't honor your request. The implied train of thought is something like this

(You) Couldn't you explain this just one more time?

(The other person) Yes, I could.

(You) So would you explain it, please?

So your first example actually isn't a request with regard to the literal meaning and the grammatical structure, but it is implied that it is meant to be a request.

The first one is request because of it's question mark and the fact that the question is directed to "you" in this case.

More examples are:

You couldn’t stop at a bank machine, could you?

Why couldn't you give me the money earlier?

As you can see, the have question marks and direct the question/request to someone, usually "you" - therefore implies that it is a request

Other general uses of "couldn't":

I was so excited that I couldn't sleep, so I got up and dressed.

I couldn't see a thing earlier.
