OK i dont know if its the middle of my brain or the back, i know its on the right hand side though. IT HURTS. hurts whenever i think rigorously, or whenever i do my homework, or whenever im trying to solve ANYTHING. I've taken regular breaks every hour for 15mins whenever I study, in class i...

oopht. mkays ill take your advise! happy attitude it is. yeah i can tell. but im definitely studying hard, listening and staying away from my friends in class.

in my situation, i never paid attention in class, never listened, never did jackshit. but i "just" got the marks so im allowed to do extension 1 maths. i got a test tomorrow, full asking questions all over the forum. so yeah, i dont have any foundation. ROFFLWAFFL

OH. stupid question. LOLS

but then what do i do with the 7x?

y = x^2+5x+1 y=7x+9 how to solve this stimultaneous?

ohhhh thanks. so it actually was the answer i got afterall :L

woops i just realised i made a mistake in the question. i just edited it. \frac{2x^2-8}{y^3-27} * \frac{2y^2-y-15}{3x^2-7x+2} (im new to this latex thing)

\frac{2x^2-8}{y^3-27} * \frac{2y^2-y-15}{3x^2-7x+2} someone help factorise and simplify. my answer is really messed up. i dont think its even the answer

yeah i never paid attention during those years. hahahaha

can you explain how you got x(x-1)(x+1)? i'm not that good with factorising =/

yuhps!

they're all actually fractions. i just put in the brackets hoping people would identify them as fractions. does change anything though?

now that makes sense!

ok i figured out why we split, but i dont understand how does grouping factors work?

actually new problem, i dont understand how 27u^2 - 28u + 1 becomes 27u^2 - 27u - u + 1 and how to make it into (27u - 1)(u - 1)

btw, AWESOME and humorous explanation (y)

wow thanks. btw how do you make your text look like that?(where the powers dont have arrows and stuff)

(3/x^2-x)+(2/x^2+x)-(5/x^2-1) how to simplify? and why?

ok i dont have 1 question, but MULTIPLE questions on factorising. im really lucky that my test has been postponed till thursday. i dont know how to do it so putting up some rules (like x^a*x^b=x^a+b) to follow and tips and all the steps inbetween would be nice :) i) x^3-9xy^2z^2 ii) 2ap^3 -...
