Re: complete square.

You have 2 x^2's.


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Hi jacks

3 is the only one in the first 100 000 positive integers. If we allow non-negative integers as well, there are also 0 and 1. Those are the only ones I can find, and I'd say the only ones that are the solutions.

Hi jacks

My post above still applies. I don't have a way to prove that are the only answers...
