document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now add 1 to both sides to get the answer\r\n" );

document.write( "    x = 1 +/- 2i.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  There are two complex roots in the complex domain, 1+2i and 1-2i.\r\n" );
