Completely factor \r\n" );

document.write( "            \r\n" );
document.write( "\r\n" );
document.write( "That's the difference of two perfect squares.  \r\n" );
document.write( "The fourth power is \"the square of the square\". \r\n" );

document.write( " \r\n" );
document.write( "            \r\n" );

document.write( "\r\n" );
document.write( "But that's not finished yet, because what's in the first \r\n" );
document.write( "parentheses will factor some more.  It is the difference\r\n" );
