0 Guest Posted March 11, 2011 Report Share Posted March 11, 2011 It's not like that Lottie T. You've just added the numbers, you have two multiply them. If you did so, you'd get an answer soooo long. The good thing is, there is an x-x in between, so the answer to the whole expression would be zero! Quote Link to comment Share on other sites More sharing options...
