i need someone to tell me if s((s+1)(s-1))/6 (G+1) is more simplifyed than this: s(s squared - 1)/6 (G+1) and can you include these double brackets and are they in the right place? thanx


Is this quadratic equations?
I'm doing them now and they're HORRIBLE! I HATE MATHS!

yep thats correct
i got it to be G/12 but it was very long-winded/lots of methods used so probably wrong
