Spot my mistake and fix it so that it matches with the correct answer. The problem is calculus based.
The problem is: what is the integral of [1/root(x^2-9)]dx? The image is posted below. The answer is supposed to be ln |(x+root(x^2-9)| +C. Obviously I got pretty close but I can't seem how to eliminate the 3 in the solution. I'm genuinely stuck at this problem. I also apologize that I set the time to less then an hour but I really need to get this done to tonight.
