Use:
+log%28a%29+%2B+log%28b%29+=+log%28+a%2Ab+%29+
and
+log%28a%29+-+log%28b%29+=+log%28+a%2Fb+%29+
-----------------
+log%28x%29+%2B+log%28+x+%2B+3+%29+-+log%28+x%5E2+-+9+%29+
+log%28x%2A%28+x+%2B+3+%29+%2F%28+%28+x%2B3+%29%2A%28+x+-+3+%29%29+%29+
+log%28+x%2F%28+x-3+%29+%29+
Note that +x+=+3+ is not allowed

(log x + log(x+3))-log(x2-9)=log(x(x+3))-log(x2-9)=log(%28x%28x%2B3%29%29%2F%28x%5E2-9%29)=log(%28x%28x%2B3%29%29%2F%28%28x-3%29%28x%2B3%29%29=log(x%2F%28x-3%29).
