I still haven't sat down and tried one. Hoping for 95+ hsc mark, what raw mark is that (percentage or x/84)?

You got the -3 and 2 part. You gotta remember that a+1 is the other root for each case. I.e. Sum of roots = -3+(-3+1) and sum of roots = 2+(2+1)

I got -1 and 3, you can check if you got it right by substituting these n vales in the original equation and solve it to check if the roots are consecutive

Let roots be a and a+1 Addition of roots = 2a + 1 = 5(n-1)/2 Product of roots = a(a+1) = 6 Solve equation for the 2nd equation. The substitute both values of a into the first one to find n. There are two n values

was @ thread and all the posters, assumed you're all male

when they ate the apple Oh wait...that didn't happen

Yup, you chose to have them, you chose raise them. I.e you volunteered to raise them. hence work in raising them should not involve money or even be seen as being worthy of some cash

So there should be wages for raising kids. That what you saying?

so anne you see effort in raising kids is worth the same (or some) value as paid work. And it's not like fathers don't raise the children

lol wtf!

More alkaline as the reduction of water gives hydrogen gas and hydroxide ions. Pretty sure that's what happens because you see bubbles

That's using the fact that every mole of citirc will produce 3 moles of hydronium ions, which doesn't happen

damn what other figures do we have to memorise?

^nice solution though for the second question, it's not more on what's incorrect but what can't be deduced

Markers are smart enough to follow someone's reasoning regardless on how they express it (assuming the reasoning makes sense). If not then what the fuck they should be

Solve or factorise? Factorising is a step in solving equations. 5(x^2 + x +1) is the LHS factorised @ nerchio what paper was that from?

Re: Einstein's going down, physicists! That is a possibility

Spiralflex is pointing out that the question didn't give the bounds and that you found the bounds with the given answer and hence was able to post the solution OR you've done it before

Re: Einstein's going down, physicists! HAHA that is a good one! Well Einstein did make his theories based on one assumption.

beast mode lol I'm sure i'll be in beast mode when it's closer to the English exam
