This topic is locked. If you want to discuss this question please re-post it in the respective forum.

If a question states (x+y)^2 is divisible by 9, is 0 considered divisible by 9

In the case above x + y = 0

Is that possible?

0 has infinite factors so I think 0 is divisible by 9, but 9 divided by 0 is of course undefined.
