You can put this solution on YOUR website!
There's the obvious difference (I hope you can figure this out), but also, adding radical expressions is more general because the radicals could be in the denominator as well. Or, you might have to simplify something like\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "by rewriting sqrt(12) as 2sqrt(3), something that you might not be doing with polynomial addition. \n" ); document.write( "

\n" );
