Hey Deborah,
If I understood your question correctly, then the denominators are
the same so we can just add the tops together.
4ax + 2a - 4b - 3ax - bx - a + 3b = ax - bx + a - b
And the bottom is the same.
Now things get a little harder but here is what I recognized.
On the bottom and the top we have a lot of a-b type patterns, so
let's factor out an a-b on both the top and the bottom.
so we have:
(a-b)(x+1)
-------------
(a-b)(x^2 + 3x + 2)
See if you can work it from there.
