Which expression is the same as 9n+ 3 after combining like terms? :
 
1. 10n^2 - n^2 - 3
2. 3n +7 - 4 + 3n
3. 18 - 15 + 4n + 5n
4. 7n^2 + 2n + 6 - 3

If 7n^2 + 2n + 6 - 3 doesn't have any like terms, it would make it hard to make it the same as  9n+ 3
Another way to tell if they are different would be if you can find any values of n for which the expressions evaluate differently.

(but can you combine anything in  + 6 - 3 ?)

Wouldn't combining "like terms" be similar to?
2y + 5y = 7y
or 8 - 5 = 3
or x^2 * x^3 = x^5

I might call the last combining like factors rather than combining like terms, but yes.

ozo,
I agree with your terminology, which is why I put "like terms" in quotes just to match the way the question was worded.

naseeam,
