I found it alright apart from the last question. I stuffed up roots of polynomials, but I knew where I went wrong. Hopefully I get some method marks ( I had a sign error). There was some other questions like I was expecting a nice number but I got a horrible answer, like the value of b on the equidistance question I got some **** like sqrt(68/3) which doesn’t seem right, but I think I used the correct method. Most of it, I think the method I used was correct, but the final answer is wrong. I’m prone to making stupid mistakes like sign errors
