    Your work looks find for problem 3b. What do you get for problem 3c?

    Note that homework questions must be posted in one of the Homework sections, not in the technical math section. For such problems, you must also use the homework template. Please refrain from posting images of your work. Instead, type the problem and your work.

    For 3b, I think the goal is to actually expand the expressions in the parenthesis, starting with (t-2)^2 = t^2 + ??? t + ??? ..., then combine with the remaining terms. For 3c, use the answer from 3a.
