\n" ); document.write( "\n" ); document.write( " $\"sqrt%28+%28+2-+sqrt%28+7+%29+%29%5E2%29\"$   has two values.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "One is    $\"2-sqrt%287%29\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Another is    $\"-%282-sqrt%287%29%29\"$ = $\"sqrt%287%29-2\"$ .\r
