Nice little Maths exam today, was alright overall.
But guys, answer this:
Hannah eats 2 orange sweets. Work out n2 -n - 90 = 0.

N=30 or what?

10? :L
Don't see what the problem is? I'm relatively shit at maths and it was pretty obvious? ( Assuming I'm right, and not missing something?)

N=90? 90*2=180-n(90)-90=0. This is algebra one guys...

I was on a roll up until this question.
F*ck Hannah, she's a fat bitch and she needs to stop eating sweets.
RE: #EdexcelMaths - Jono - 06-04-2015
The question isn't correct.
The actual question, (The one I got my answer from) is:
n ² - n - 90 = 0 ?
RE: #EdexcelMaths - Tomo - 06-04-2015
Yeah Jono that was it.
I factorised it to get (n+9)(n-10)=0
Then I worked out that n=10
If you then substitute 10 back into the equation it works:
10² - 10 - 90 = 0
100 - 10 - 90 = 0
90 - 90 = 0
That was for part b) of the question. I had no idea how to do part a)

Easy way: F*ck up math and study something else instead.
Hard way: Sit on your butt until it is used up
RE: #EdexcelMaths - yarrrs - 06-04-2015
Should have put a carrot to represent that being an exponent.
