Notice that you have two - signs in a row.  Was that a typo, and
there should have been only 1 - sign? 
I'll assume so, that you mean this:



The first and last terms are like terms, so 
combine them:  1*log(x)-2*log(x) gives -1*log(x)




Move the -1 coefficient of the first term to the
exponent of what the log is of, which is x, making
the x become x-1



Write the sum of those two logs as the log of a
product: 



Simplify by adding the exponents of x:
