===================


Ignore the post by @josgarithmetic.


        The meaning of your question is unclear.
        The tutors  SHOULD  NOT  guess what is the meaning of your question,
        and from the context,  it is  IMPOSSIBLE  to guess.
        In this situation, guessing is against of common sense and against the rules of functioning of this forum.


Re-post your assignment to the forum again,  but this time write clearly,  what you need/want to get.

What kind of value?
Intersection points?

f%28x%29=g%28x%29
3x%5E2%2B2=x%5E2-x
3x%5E2-x%5E2%2Bx%2B2=0
2x%5E2%2Bx%2B2=0

If any, expect x=%28-1%2B-+sqrt%281-4%2A2%2A2%29%29%2F4
x=%28-1%2B-+sqrt%28-15%29%29%2F4------------not "Real" numbers; but is this anything like what you are looking for?
