None of your attempts show you doing that. What did you get?

(Y+1)^2

9. You can't square y and 1 separately you have to do (y+1) ^2

10. When you square one side of the equation you are squaring one thing, that is the "y+1", hence . You can't just square the y term and square the 1 and add them.

Why can't I square them separately? They aren't together? :confused.

Yes they are. Say for example you had something equal to 1+2. If you square them separately and added you would get 5 when clearly it is 3^2 ie 9

16. expand (y+1)^2
you square y+1 because the other side everything is rooted.
