\"48x%5E3+%2B+42x%5E2+-8x+-7\".....group first and third term together, then group second and fourth term together\r
\n" ); document.write( "\n" ); document.write( "\"%2848x%5E3-8x%29++%2B+%2842x%5E2+-7%29\".....factor out common \"8x\" from first group, and common \"7\" from the second group\r
\n" ); document.write( "\n" ); document.write( "\"8x%286x%5E2-1%29++%2B+7%286x%5E2+-1%29\".....combine like terms\r
\n" ); document.write( "\n" ); document.write( "\"%288x%2B+7%29%286x%5E2+-1%29\".....
