Essentially, you've got your equation to the normal now from part a) you're looking for where it cuts the curve y^2 = 4ax again, what can you do to find out where they intersect?

no idea. can you tell me withut riddles please.
i've tried substituting it into both the normal equation and the y^2 = 4ax one, but no luck.

You're totally on the right lines, there's two substitutions you can do, one which is much longer i.e. subbing in y^2, because you'd have to expand and simplify, why not try subbing in x = y^2/4a?
