Homework Equations
The Attempt at a Solution
The part I am stuck is where I highlighted. The first question: The whole thing is squared so I don't know how to do it with the squared in the way.
The second question: It is just plain weird. I think I am not supposed to do that for the highlighted part.
The answer for first question is : 4 (-4,4)
The answer for second question is : infinity (-infinity,+infinity)
