n^2-4 can be written as =(n-2)*(n+2) so we'll have (n-2)*(n+2) ------------= n-2 (n+2)

I need to simplify the whole equation. So I would have to multipy that to n/3n-6

4. angela210793

oops sorry i 4got the rest of the problem

5. anonymous

It's okay.

6. angela210793

(n-2)*n/3n-6=(n^2-2n)/(3n-6)

Is that the whole answer? I'm looking for just one answer that is simplified. I don't know the name of this kind of math method though...

8. anonymous

Maybe an example would help?

9. anonymous

3n -6 = 3(n-2) $\frac{n(n-2)}{3(n-2)} = \frac{n}{3}$

For example, y^2/12x is in Simplest Form

11. anonymous

the math method is just factoring and reducing by cancelling

12. anonymous

Yes, that's it!

13. anonymous

I don't understand how to do the problem.

14. anonymous

break it down, look at each term and try to factor it then cancel identical terms on top and bottom

15. anonymous

best way to learn is to practice factoring

OKay, I saw your above answer, thank you! I think i can figure it out myself now
