\r\n" );
document.write( "Put a minus sign between them keeping them in parentheses:\r\n" );
document.write( "\r\n" );
document.write( "(5x² + 10x - 5) - (4x² - 6x + 1)\r\n" );
document.write( "\r\n" );
document.write( "Remove parentheses.  The second parentheses is preceded by a -,\r\n" );
document.write( "so change the signs of all terms inside when removing parentheses:\r\n" );

document.write( "5x² + 10x - 5 - 4x² + 6x - 1\r\n" );
document.write( "\r\n" );
document.write( "Combine like terms 5x² and -4x² as 1x² or x².\r\n" );
document.write( "Combine like terms 10x and 6x as 16x.\r\n" );
