Answer 1

Here is the question and what I have so far
Thanks

Answer 2

I think they want you to notice that y is not of the form C x^4, where C is a fixed constant. You have a solution with C=1 and C=-1 (i.e. 2 different values). So all you have to do is say is the solution is not of the form C x^4, because you do not have a constant C.

Answer 3

Ah ok. Is that all thanks :D
