I've attempted this problem at least 10 times, and keep on getting the same answer, which is incorrect according to the program I have to submit it in.

The integral given is:

1/ (x^2 + 0 - 25)

The answer I'm calculating is:

(-1/10)ln(x + 5) + (1/10)ln(x-5) + C

Any help would be great, because I am truly lost.
