document.write( "\r\n" );
document.write( "In this way you will find the roots  \"x%5B1%5D\"  and  \"x%5B2%5D\"  of the quadratic polynomial  p(x) = \"x%5E2+%2B+7x+%2B9\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then factorize  p(x) = \"%28x-x%5B1%5D%29%2A%28x-x%5B2%5D%29\".\r\n" );
