I need to condense the following logarithm: $\displaystyle 4[ln(x) – ln(x + 5) – ln(x – 5)]$ Is this one supposed to be a trick question?

Hmm, it appears there are minus signs in there? Does the corrected LaTeX show a true representation of the question? $\displaystyle ln(x)-ln(x-5)-ln(x-5) = ln(x) - [ln(x-5)+ln(x+5)]$ $\displaystyle ln({\frac{x}{x^2-25}})$
