    You can expand and simplify the expansion under the square root.
    And you were asked to apply implicit differentiation. How would you do it?
    Please, type in your work.

    @iwantcalculus, there's the "brute force" way, which is how you are proceeding, and there's a different way that involves implicit differentiation. What's another way to write the equation you're starting with.
    Absolutely. Posting an image of your work doesn't let us insert a comment at a particular location where you might have gone wrong.
