there are technically infinitely many solutions.
For example: i, -i, and any positive number. i is imaginary, so it could be either positive or negative (it’s controversial).
In addition, the set 33, 44, and 711711 also satisfies the question. Acording to WolframAlpha, for any two numbers aa and bb whose product is not 1, the third number equals a+bab−1a+bab−1. This applies to any real numbers ..
