Well this is my worst area. Not sure why though. Here's the latest problem I'm stuck with. 1. The problem statement, all variables and given/known data log(3-x) + log(3+x) = log(5) 2. Relevant equations 3. The attempt at a solution log(9-x^2) = log(5) The answer is plus/minus 2, but I'm really not sure on where to go from here. This is the stuck point.
