First, factor the numerator.

Then, divide out any common factors. In this case, is common in both the numerator and denominator. So, we end up with:

Do this one the same way.

There are no common factors here, so nothing cancels out. This cannot be simplified further.

We need to find the common denominator. Since they're both different the common denominator will be

Now rewrite each fraction using the new denominator. We do this by multiplying this common denominator by each term; then put that result over the common denominator. Like this...

Let's rearrange that second fraction to get both denominators to look the same.
