document.write( "Follow the instructions and factor completely FIRST.\r\n" );
document.write( "\r\n" );
document.write( "x²-9 factors as (x-3)(x+3) \r\n" );
document.write( "\r\n" );
document.write( "x² - 6x + 9 factors as (x-3)(x-3) [or (x-3)²]\r\n" );
document.write( "\r\n" );
document.write( "So the expression (x-3) goes into both (x-3)(x+3) and (x-3)(x-3)\r\n" );
document.write( "\r\n" );
document.write( "They both contain factor (x-3) so that's the GCD.\r\n" );
