Your answer should include many observations, including:
They are both Defintions of the Derivative.
i. uses Hana's Method.
ii. uses Hanah's Method.
In both cases, the function that is being differentiated is f(x) = (x + 1)(x + 2).
Once f(x) is determined, both can be evaluated using the Power rule, avoiding lengthy Algebraic manipulation.
i. Refer to hints in problem 3-64.
ii. Refer to hints in problem 3-92.
