Nice little Maths exam today, was alright overall.


But guys, answer this:

Hannah eats 2 orange sweets. Work out n2 -n - 90 = 0.

[Greed^]

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?)

[yarrrs]

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

[Tomo]

I was on a roll up until this question.

F*ck Hannah, she's a fat bitch and she needs to stop eating sweets.

[Jono]

The question isn't correct.

The actual question, (The one I got my answer from) is:
n ² - n - 90 = 0 ?

[Tomo]

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

[yarrrs]

Should have put a carrot to represent that being an exponent.
