$\"ln%28x%5E%282%29-5%29=ln%282x%29%2Bln%28x-3%29\"$
\n" ); document.write( "then
\n" ); document.write( " $\"ln%28x%5E%282%29-5%29=ln%282x%28x-3%29%29\"$
\n" ); document.write( "then
\n" ); document.write( " $\"x%5E2-5=2x%5E2-6x\"$
\n" ); document.write( "then
\n" ); document.write( " $\"x%5E2-6x%2B5=0\"$
\n" ); document.write( "then
\n" ); document.write( " $\"x+=+%286+%2B-+sqrt%28+16+%29%29%2F%282%29+\"$ =
\n" ); document.write( " $\"x+=+%286+%2B-+4%29%2F%282%29+\"$
\n" ); document.write( "then x=5 or x=1
\n" ); document.write( "but if x=1 then $\"ln%28x%5E2-5%29=ln%28-4%29\"$ ( does not exists)\r
