The lowest common denominator for the three terms is \displaystyle (x-2)(x+3) and we expand each term so that all terms have the same denominator
Now, collect the terms in the numerator
Note: By keeping the denominator factorized during the entire calculation, we can see at the end that the answer cannot be simplified any further.
