Do it like this one:
\n" ); document.write( "===================
\n" ); document.write( " $\"log%282%2C%28x%2B3%29%29+%2B+log%282%2Cx%29+=+2\"$
\n" ); document.write( "Adding logs --> multiplication
\n" ); document.write( " $\"log%282%2Cx%2A%28x%2B3%29%29+=+2\"$
\n" ); document.write( " $\"log%282%2C%28x%5E2%2B3x%29%29+=+2\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"log%282%2C%28x%5E2%2B3x%29%29+=+log%282%2C4%29\"$
\n" ); document.write( " $\"x%5E2%2B3x+=+4\"$
\n" ); document.write( "Now it's a quadratic.
\n" ); document.write( "Check both zeroes, don't accept the log of a negative number.
\n" ); document.write( " \n" ); document.write( "

\n" );
