You'll notice that the constants in (iii) matches the one given in the equation. Its basically the same equation, except now your x is subbed out with x^2.
For your part (ii), f(x) = 0 should have allowed you to arrive at a few possible equations where x = insert value (which are your answers to this part).
All you have to do is use these same few equations again but now use x^2 instead of x, then continue to solve for x from there.
I didn't do your earlier parts so I don't know what your (ii) values are but just take note of exclusions (i.e. when you have multiple equations where the value of x necessarily contradicts each other).
