Math help please.

This is grade 11 math and I'm stuck on a equation involving adding and subtracting rational expressions

The question is

6 + m + 1 + 5m
---------- ----------
4(m + 1) 2(m-1)

I don't know what to do with the denominator when there's a number placed in front of the binomial
thanks, i appreciate your help
The answer is 11m^2 + 17m - 4
---------------------
4 (m-1) (m+1)

I just wanna know how to deal with a number beside a binomial in the denominator when adding and subtracting rational expressions ...

[quote=myLOVE]I'll do it on paper right now.
The equation I just put on my first post was unfinished.[/quote]

Thanks, I really appreciate it

[quote=myLOVE]You multiply the 4 and the 2 if you're having a common denominator.
But make sure you cross multiply first.[/quote]

The answer in the textbook is different from what you got.
I edited the answer

[quote=DDRfreak2293]They just have to have the same terms. So your denominator is going to look like 4(m+1)(m-1).[/quote]

I dont understand. Where does the 2 go?
