I don't understand your point. I know it can only be factorised in this way. It was only 1 mark, the original spec should be adjusted, as it was the expand and simplify was 2 marks, for expanding correctly, then simplifying.
Not quite sure what you mean? all you had to do is factorise for 2 marks, it's an easy picked up. Are you saying WHILE there wasn't anything else you had to do, their SHOULD have been?
2. Lol, what I did is correct, someone must have wrote the wrong question earlier, cuz I was answering it, I did my maths GCSE and further maths last year. You are correct for your question. Look up like 3-5 questions

Wrong.

3(m+4)-2(4m-1) expanded is 3m+12-8m-2 = -5m+10
(Original post by 34908seikj)
Wrong.

3(m+4)-2(4m-1) expanded is 3m+12-8m-2 = -5m+10

then what was "your" question? seems irrelevant as that was the question that was on the exam paper..?
4. All I am saying is that the mark scheme is incorrect. The factorise was 1 mark and the expand and simplify was 2 marks. It reads the other way round.

You're right.

I was thinking the same!
Don't you just love how I say it's the easiest marks ever only to realise I didn't write the formula out so will probably drop a mark for that 😂
7. There's nothing to simplify from that, y outside must= 0 or y inside must =7

Thats assuming it = 0, but your point still stands
9. (Original post by DaveMoishe)
You may get one mark, as if you rotated it 90 degrees and by the correct point, it is only the anti bit you got wrong.
yeah that's what I did. i always go to confident and never read the question
10. and simplify 3(m+4) - 2(m+1) (1 mark) Written by a person earlier. I was just trying to help, cuz what he wrote to the question he wrote was wrong .

11. I noticed for 19a) part 1 and part 2 is 3 marks, how is that divided between the two sections?

part one was one mark since y=0 and part 2 was 2 marks because you had to draw a line on the graph and at 4 to the equation - not in that order
13. It's the one with the graph to find the solutions from the graph. I'm assuming 1 mark for the first bit, then 2 for the next bit?

Edited my other comment
15. Hii can someone please help me Im really worried, for the vector question the answer is a+b but I never put the lines_ under the vectors, will I still get the mark??????Pleaase someone answer ASAP

If anyone is struggling with a question, tell me the details of the question and I'll provide an answer for you to stop ye debating (hopefully)

hello, with question 2b) [basically the question with rotate 90 degrees anticlockwise], did the person do it wrong who did the paper? because it looks like it should be down one more layer? because they went three up and one to the left from point (0,1), when surely they should have gone two up and one to the left? Please tell me otherwise :-)

You will probably get benefit of the doubt. However you didn't need any notation for a+b (for example) so you'll be fine

Thanks, sorry to be annoying but, I noticed that for question 7) the answer was no Angie hasnt got enough tins, because she needs 10litres and only has 7.5-- However I put that she needs 4 tins and only has 3 tins, will I not get full marks for this even though I providing my working out to get that 10 litres are needed? thanks

You will, you don't need to put the lines for things like a+b, only for showing a point to another point like OB
