\r\n" );
document.write( "\"sqrt%28+%28sqrt%2821%29-2sqrt%287%29%29%5E2%29\"  has TWO values.\r\n" );

document.write( "One value is  \"sqrt%2821%29-2sqrt%287%29\".\r\n" );

document.write( "Another value is  \"-%28sqrt%2821%29-2sqrt%287%29%29\" = \"2sqrt%287%29+-+sqrt%2821%29\".\r\n" );

\n" ); document.write( "\n" ); document.write( "Calculations that \"josgarithmetic\" does in his response, are absolutely unnecessary.
\n" ); document.write( "They do not lead to the simplest form.
\n" ); document.write( "In opposite, they require to be simplified further.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So, writing by \"josgaritmetic\" is totally out of the goal of this assignment.\r
