@Yuki (or whoever gets to it first) so would you use the same techniques you were showing me for this one? it is in an attachment >.< sowee im confused... :P

anonymous · Answer

the first one is the equation your simplifying the next 3 are the options :)

anonymous · Answer

Eh, I would just factorise the first term, then multiply by the inverse of $$n+4 / n-3$$

anonymous · Answer

So the first term reduces to (n+4)^2/(n-3)^2 after factorising then you just multiply that by (n-3)/(n+4) which cancels the first to (n+4)/(n-3)

anonymous · Answer

Ahhh i see i would have gone with C i wish there were a quicker easier way to find the answers to these things that werent so dang complicated!! :P lol but thanks a bunch just helped me slot!! :D

anonymous · Answer

your welcome :D

anonymous · Answer

so then the answer to this one would be : wait here i will attach them can u do the last two with me? pls? :)

anonymous · Answer

OK

anonymous · Answer

option C = 1

anonymous · Answer

OK so factorise (n^2 + 3n + 2) to (n+2)(n+1), so it becomes $$((n+2)(n+1))\div2$$ then multiply that by the reciprocal of (n+1)/(2(n+2)) which is 2(n+2) / (n+1) , both the 2s cancel and the (n+1)s cancel so its just (n+2)^2

anonymous · Answer

Ahhhh alright i see the "pattern" or whatever lol okie dokie last one and its on long division UGH :P i stil cant get the hang of it :P

anonymous · Answer

Option A = x + 5 
Option D =  x - 7

anonymous · Answer

OK well can you do long division? Kinda hard to show it on here but I can try

anonymous · Answer

:P i hate long division URGHHHH

anonymous · Answer

ok so do you think you could attach the steps?

anonymous · Answer

Lol 
         x  -  9
        ______________
x+7/x^2 - 2x - 30
        x^2 + 7x
        --------
               -9x - 30
               -9x - 63
             ----------
                        33  <- remainder

so it's
x - 9 + 33/(x+7)

Ok im pretty sure i get it now, well more than i got it before :) lol thanks :)

anonymous · Answer

i always get so wrapped up in the solving underneath the division thing i forget about above it ^^

anonymous · Answer

haha!! thx!! :)

anonymous · Answer

Yeah.. I remember doing long division of polynomials last term, it's annoying cause I never used to use long division in lower school I just did the divisions in my head so I had no idea how to do long division. Good luck and you're welcome..

yea ikr lol thx :)
