Use the following logarithmic property:
\n" ); document.write( " $\"log+a-log+b=log+%28a%2Fb%29\"$
\n" ); document.write( "So
\n" ); document.write( " $\"log+%28%28x%5E2-1%29%29-log+%28%28x-1%29%29\"$
\n" ); document.write( "= $\"log+%28%28x%5E2-1%29%2F%28x-1%29%29\"$
\n" ); document.write( "= $\"log+%28%28x%2B1%29%28x-1%29%2F%28x-1%29%29\"$
\n" ); document.write( "= $\"log+%28%28x%2B1%29cross%28%28x-1%29%29%2Fcross%28%28x-1%29%29%29\"$
\n" ); document.write( "= $\"log+%28%28x%2B1%29%29\"$
\n" ); document.write( " \n" ); document.write( "
