Yep, in the Maths in Focus textbook. Exercise 4.2, Question 2. It's not some sort of factorisation exercise, it's just part of the Exponentials and Logarithms chapter where you have to find the second derivative of http://puu.sh/2klat

Also, you left the 6(e^2x) term and the e^2x term separate, they should just become 7e^2x, right?

I know how to factorise most things, I think this was just a little more complex than the others.

Ohh, I see what's happening now. Thanks :)

...but what did you do to get that answer?

The back of the book says it becomes: http://puu.sh/2kkPs They also had the 168e term before the 28e term before it was factorised, if that helps with anything.

Discriminant ≥ 0, then real roots. Discriminant > 0, then real, distinct roots. Discriminant = 0, then 2 real equal roots, or 1 real root. Discriminant < 0, then no real roots. ≤ 0 isn't really used.

Oh, I completely forgot about that. Thanks for replying!

What if the person ranked 1st for assessments bombs out in the exam and gets like 30%, while everyone else gets higher? Does it mean everyone's moderated assessment marks become 30 and below?

What about a case of multiple discovery/invention, where two or more people independently come up with the same idea? I'm sure it happens plenty of times in the HSC where definitions come close to being word for word, or exactly word for word.

I've made two quick graphs using https://www.desmos.com/calculator/ and the Raw Mark Database: http://community.boredofstudies.org/showthread.php?t=269611 Effectively you can click and run your cursor along the (very rough) line of best fit to see what raw marks in certain subjects are when...
