For the polynomial question, is it possible to factorise the quadratic, or do you just leave it in the (x+1)(x-1)(3x^2+4x+2) format?
My teacher said it couldn't be factorised any further so it should be right. I don't see where the 5 marks come from though

Yeh I got that answer, and I expected to have to do more since there was so many marks available.

So it says to "show all working", see if I just wrote the midpoint without writing the starting equation (M=(X2-X1/2 etc...) - would I still get the mark?

I did this too, never actually thought to show my working completely for just finding a midpoint. Hopefully we’ll still get that mark

Nice! Yeah, all the past papers I've seen give the mark for just stating the midpoint - so that's why I did it. But then I got home and seen show all working in bold on the front of the question sheet. Hopefully we do get it

Not a good maths exam Really made unfair when you compare the standard of this exam compared to the last 3 ones ... Not even the specimen paper for this year is representative of the level of difficulty in this one lol.

Yeah, I put it into photomath and it came out with (x+3)(x-1)(3x^2+4x+2) which is what I put. Should only have been worth 3 marks, 4 at a push.

Thought the papers went well, I’m just uncertain of the question in paper two asking about the domain - what did people put for that? I just repeated the domain from above?

I wasn't sure about that one, but I put -1000 ≤ x ≤ -1, but I have no clue if that's right.

Well I needed a B but that’s that gone hahaha don’t even think I have a C.

Was anyone getting weird fractions for paper 2 q1???

I got the point of intersection as being (5, -2) or something. But apparently I went from A band 1 to C band none today so don’t take my word for it.

did anyone manage to do part a) of the optimisation question in paper 2?? my answer was 16x^2 + 3000/x. I don't understand where the 4000 comes from
also, the last question in paper 1 was crazy
