Now, in looking at the numerator, find the lowest common factor to simplify. What number can go into 12, 16, and -8? There are numbers that can go in, like 2, but since 4 also can go in, we would use that one because it is larger. Those numbers also have the letter "a" attached to each. You would take 2 a's because every number has at least 2 a's. So, now you have 4a, you would divide that into the equation
So, to simplify it would look like this:
Now, you would cross out the "4a" and you're left with your answer. (The negative sign would transfer to the top.
