\n" ); document.write( "and then
\n" ); document.write( " $\"x+=+%2828+%2B-+sqrt%28+1568%29%29%2F%2898%29+\"$
\n" ); document.write( "and simplified as
\n" ); document.write( " $\"x+=+%2828+%2B-+4sqrt%2898%29%29%2F%2898%29+\"$
\n" ); document.write( "reduced we get
\n" ); document.write( " $\"x+=+%2814+%2B-2sqrt%2898%29%29%2F49\"$ \n" ); document.write( "

\n" );
