shouldn't 4(d) be +20 at the end because that was the remainder? that's what I got and it seemed to work.Post rating:1

First post here, hello!
Some of your solutions for six were for question seven if I recall correctly  finding the tangent and the coordinates of Q were specifically to do with the integral if I'm not mistaken?
Question six had you solve the quadratic for 1 ± √ 5, sketch the graph, do a 1 mark 'show that' question and then solve the inequality, I think it just needs to be rearranged a bit.
