how many marks do ye think i'll lose? i mean, will it qualift as a blunder?
You read the question wrong. But effectively carried out the same method and answered the question correctly. So, I think it would very harsh to dock you anything more than a mark.0 -

Probably a misreading, you should only lose a mark as it didn't oversimplify the question.0 -

ah no, you see lads what i did was i took the right answers from the part (i)
and did something like this with them
(x+2)-1= x+1
(x-1) -1= x-2
(x-3)-1= x-4
and used those roots instead of
x=-2-1= -3 (x+3)
x=1-1=0 (x)
x=3-1=2 (x-2)
you know? kinda gutted here. ye still think that'll only lose me a mark or two? 0 -

Ah so you took 1 from the factors.. that's a tough one to call alright. You do realise the max you could lose is 3 marks though? So it's not too bad. Personally, I'd classify that as a blunder.0 -

I did the exact same, so annoyed at myself
Hopefully they won't be too mean 0 -

thanks lads, i was starting to get worried but 3 marks aint TOO bad...was hoping for full marks in paper 1 to give me a nice cushion for paper 2 (got 98% in P1 in the mocks, only 85% in P2) but ah wellStalin and rugby wrote: »That almost caught me aswell, looks like blunder to me bro -3.

Hey guys need your help.
For 2.C , I misread the damn question and for some damn reason when i multiplied across by x , i had x^2 + x =2x, i brought across the 2x and argued my case that it must be greater than zero.... i did this for both part i, and part ii, i am very very annoyed with myself, this is without a doubt the reason i will not get a b3 in my maths
I'm just wondering what marks will I get for each answer?
For c, part iii, i think i got that one right.0 -

-1 as long as the question was not oversimplified0 -

So I take it that 3 off the answer?
You gotta stop worrying about that stuff bro, like I said if the question isn't oversimplified and the method is correct where you just wrote down the wrong number or whatever it's -1.
But tbh none of us can tell you for certain, forget maths p1 go take a tug get up early tomorrow morning, head down paper 2 bro Gotta work!
