  Find ff(x) in terms of a and b then proceed to compare coefficients, derive some equations in terms of a and b, then solve them.

  I believe it's a^2x + ab + b = 9x - 28
  But I don't know where to go from there

  Equate the coefficients of x and the constant term.
  
  So if you had then you'd have and . In this case, you have . So what can you get?

  Compare the coefficients of and because they must be equal to each other on both sides.
  7. Can anyone help me with equating the coeffients? I'm rusty and just don't know how to move forward with it

  There is literally an example above my post. Use it, it isn't a complicated technique and makes sense.
