Please look up "factoring" using Google.
My purpose was so you could read up and learn the basics.
You need to do that: I can tell from the work you posted.
Would be senseless of me to type pages of stuff on the basics,
when you can get it using Google.
Good luck and have a good day.
I have actually completed the sum,I just got confused.
You should know that if I typed factoring in google thousands of results would show up.I simply wanted someone to guide me back on course,not spend hours looking on google.
After all its called the mathshelpforum not the refer to google forum.
Have a nice day too
