First attempt to understand your equation is that the base is 3. If this is the case, then $\"log%283%2C%28x%2B6%29%28x-6%29%2Fx%29=2\"$ .
\n" ); document.write( " $\"log%283%2C%28x%5E2-36%29%2Fx%29=2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"3%5E2=%28x%5E2-36%29%2Fx\"$
\n" ); document.write( " $\"9x=x%5E2-36\"$
\n" ); document.write( " $\"x%5E2-9x-36=0\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=%289%2B-+sqrt%2881%2B4%2A36%29%29%2F2\"$
\n" ); document.write( " $\"x=%289%2B-+sqrt%28225%29%29%2F2\"$
\n" ); document.write( " $\"x=%289%2B-+sqrt%289%2A25%29%29%2F2\"$
\n" ); document.write( " $\"x=%289%2B-+15%29%2F2\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"highlight%28x=-3%29\"$ or $\"highlight%28x=12%29\"$ . \n" ); document.write( "

\n" );
