Simplify

ab + 3a² + 5b - 2a² -ba

11a² + 3a + 5b +6ab -a² +5a -5b

8ab² + 3a²b - 5ab² + 6ab + a²b + 5ba

ab -3ba + 5ab² + 6b² + b²a + 5ba

please please do my homework for me!

Do it yourself.

Just take out common factors like a, a^2 etc...

That's all you need to know, now do it yourself

I've just finished my Maths A-level. It looks like either higher level O-level maths or the start of pure maths (either C1 or C2). Given that this thread was posted when it was, I'd guess this is A-level C1 because I know the colleges started term again a few days ago.

I should be in the OcUK detective squad :cool:

lol

(I was joking, the things those guys can do when investigating things scares me)

I'm guessing we should expect more of these threads with school starting and all..

cheers for all the help anyway guys. your knowlege knows no bounds etc etc

Is that seriously A Level maths? Because I'm pretty sure I was doing that around GCSE level.

Hxc · 7 Sep 2008 at 23:40

It's the introduction to A-Level maths, we did similer in our first hour on friday. Basically just telling you what you should know.... it's fairly basic stuff.
