In my opinion, this did belong in the other thread, since it is the same kind of problem, and you just need to apply the same method, so seeing them together helps us. I'll repeat here what I said there:

But you should just do one step at a time! Put this equation into the form Ax^2 + Bx + C (that is, a general quadratic), and equate it to 3x^2 – 7 = 0 as before. (Note that in the previous problem, I would have talked about Ax^3 + Bx^2 + Cx + D, not Ax^3 + Bx^2 + D, and this example illustrates why.)

Show us your results, and if it isn't clear what to do next, we can help you. Problem solving should not be dependent on having a complete plan, or on being told everything to do.
