I have not seen the question but I saw the article on BBC News.
n2 - n - 90 = 0 has two solutions : n=9 and n= -10.
Without seeing the question I do not know why it was a problem but I cannot see what relevance it has to the probability of two sweets being orange. The presenter said

This was the question:
Hannah has 6 orange sweets and some yellow sweets. overall, she has n sweets.The probability of her taking 2 orange sweets is 1/3. Prove that n^2-n-90=o

Took me 30 seconds, if you think about what you'd do if n was a number and not get scared by it it's fairly easy really.

The grade boundaries are changed every year to make a certain number of people get each grade, a petition will make absolutely no difference to anything, but sign it if it makes you feel better.

Petition isn't going to change anything...at least be grateful that you didn't have an actual impossible question in your exam, like the one in a D1 A-level maths paper a few years back

I know i have said that but what people are saying is that it wouldnt hurt to sign it if you wanted too because it might do something you never know. Lots of people are against signing it which is fine its totally an individual opinion.

Yeah of course it doesn't hurt to sign it, but again, it will change absolutely nothing...the grade boundaries are calculated on how everybody across the country did, so a petition isn't going to lower them

Doesn't seem like an individual opinion to me, seems like one person got butthurt because they did badly in their exam, made a petition, and now loads of people are jumping on the bandwagon to try to get an unfair advantage on every other year group, as fruitless as it may be...

Averagely...... almost EVERYONE got ONE GRADE LOWER then expected like some want As and they think they only got like 40 marks, others want a B and think got like 25 and other wanted a C and think they got like 29.
I want an A but I think I only got around 55-75 marks can't tell as it was quiet wordy but it will be lower then last years as everyone is complaining and not everyone complained like this last year!

The question was fine. It was a difficult one for GCSE but examination boards have been told by the government to make papers tougher.
In my earlier blog I did not know the question. The original BBC presentation was incomplete. The later explanation was better and Lewis Martin's answer was correct.
There is no need for a petition which is complaining about one question being too hard. It was hard but possible. A star stuff.

I haven't seen an unofficial markscheme but if you factorise n^2 -n - 90=0
you get (n-10)(n+9)=0
N=10 or -9
Sorry for previous typo, this is the answer

I'm not arguing against you, I'm arguing against the idea of the petition, all I'm saying is if the examining board were to artificially change grades because of the petition it's unfair on other year groups..
