help please

the curve c has equation y = x squared + 3px + 8p where p is a real constant. the straight line L has equation y = 1 - 2x given that L does not intersect C find the set of possible values of p giving your answer in exact form

What have you managed to work out so far? Or are you completely stuck?

You'd have to use the discriminant, and since the two lines don't intersect(no real solutions) do you know which form of the discriminant you'd use?
