Find the derivative of each function.
Now we need to use the quotient rule and the product rule only once each, which is much easier! We need the product rule to find the derivative of the denominator:
Now for the quotient rule:
Again, every term has at least one ex, we can cancel those out:
In this case, it makes sense to multiply out the terms because there aren't many to multiply out, and because x2 and are multiplied together and cancel to give us something nicer:
