can anyone explain how to divide in algebra? I have this problem:
(15x224+9)/(3x3)
I am not looking for someone to give me the answer straight out I just need to know how to get there.

Start in the same way as you would do long division.
Set it up as
_________
(3x3)15x224x+9
then how many times does 3x go into 15x^2, which is 5x
5x
_________
(3x3)15x224x+9
15x215x (from 5x times (3x3)
subtract
5x
_________
(3x3)15x224x+9
15x215x
________
9x+9
I hope the formatting holds. Is this OK? 
The formatting didn't work 8((
I hope you get the idea. I'll try again with dots for spaces.
