I don't see any reason to vote down. Based on the properties of the logarithmic function, there are few ways to solve this problem (or notations to write the solution).

For the moment, think of log(x^2) as being log(x*x)
We know from the rules of logarithms that
log (x*y) = log(x) + log(y)
In this case, log(x^2)-log(x) = log(x) + log(x) - log(x) = log(x)
