From the property of logarithm:
\n" ); document.write( " $\"log+M+-+log+N+=+log%28M%2FN%29\"$
\n" ); document.write( "Let
\n" ); document.write( " $\"M+=+x%5E2-4\"$
\n" ); document.write( " $\"N+=+2x-4\"$
\n" ); document.write( "So, $\"log%28%28x%5E2-4%29%29-log%28%282x-4%29%29=log%28%28%28x%5E2-4%29%2F%282x-4%29%29%29\"$ factor out
\n" ); document.write( " $\"log%28%28x%2B2%29%28x-2%29%2F2%28x-2%29%29\"$ cancel (x-2)\r
\n" ); document.write( "\n" ); document.write( "the answer is, $\"log%28%28%28x%2B2%29%2F2%29%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
