Whenever you subtract fractions, you need to have the same denominators.
Let's look at each denominator first.

So if you multiply the first denominator by (a+1) and then second denominator by (a), they will have a common denominator of a(a+1)(a-2).
Remember whatever you multiply the denominator by, you also must multiply the numerator by.

Remember this relation only makes sense when a does not equal 0,-1,or 2.
