\r\n" );
document.write( "1.  First let us complete the square:\r\n" );
document.write( "\r\n" );
document.write( "     =  =  = .\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "2.  Having this, you can re-write the original equation as\r\n" );
document.write( "\r\n" );
document.write( "     = 0,   or\r\n" );
document.write( "\r\n" );
document.write( "     = .\r\n" );
document.write( "\r\n" );
document.write( "    Take the square root from both sides:\r\n" );
document.write( "\r\n" );
document.write( "    x + 4 = +/-,  or\r\n" );
document.write( "\r\n" );
document.write( "    x = .\r\n" );
