$\"%28sqrt%2832x%29%2Bsqrt%282x%29-sqrt%2818x%29%29\"$ [Treat each radical as a term. You can add and subtract like-radicals the same as you would add and subtract like-terms]
\n" ); document.write( ".\r
\n" ); document.write( "\n" ); document.write( " $\"%28sqrt%288%2A4x%29%2Bsqrt%282x%29-sqrt%289%2A2x%29%29\"$ [So, try to make the radical terms match]
\n" ); document.write( " $\"%284sqrt%282x%29%2Bsqrt%282x%29-3sqrt%282x%29%29\"$ [Simplify]
\n" ); document.write( " $\"%284sqrt%282x%29%2Bsqrt%282x%29-3sqrt%282x%29%29\"$ [Since the radicals are now \"like-terms\" (sqrt(2x)), you can add the coefficients of each radical]
\n" ); document.write( ".
\n" ); document.write( " $\"%284sqrt%282x%29%2B1sqrt%282x%29-3sqrt%282x%29%29\"$ [Add the coefficients: 4+1-3=2]
\n" ); document.write( " $\"%282sqrt%282x%29%29%29\"$ \n" ); document.write( "

\n" );
