Algebra: Show that v, ø(v), ø(v)^2 are independent

[victoranderson]

Please see attached question.
I can finish part (a)

For part b, how can I find ø(v) ?
Although I can find ø(v1) and ø(v2) but I think it is unrelated to ø(v)...

I am sorry for creating two posts accidentally, I am just a newbie...
