A funny algebra puzzle!

a and b are real numbers

We have the following expressions:

a² - b² = 9

a.b = 3

Question: what are the value(s) for a and b ?

Good luck! And try to be among the first ones!

  • Many thanks Fons! It's indeed a little bit more complex with the dot line in a.b not being a simple decimal point...As stated for Gaetano, the final answer will be confirmed in a few days...
