Hey all, I have this mathematics quadratic identity question and the two ways of going about it give different answers. Which is correct? Question: 7x ^ 2 - 20x + 15 = A (x - 2)^2 + Bx(x-2) + C Approach 1: 7x ^ 2 - 20x + 15 = Ax^2 - 4Ax + 4A + Bx^2 - 2BX + 4A + C 7x ^ 2 - 20x + 15 =...

Hey all :) Does anybody know what date MWs are due this year? Thanks!

Hey all :) Was just wondering what the policy was for calculator errors in HSC exams? Say, you had all working out correct and showed the correct final line of working, but punched it into your calculator wrong and then got the wrong answer, do you still get the marks? An (oversimplified)...

Hey all :) For the UNSW Undergraduate Medicine/ Surgery Course does the predicted UAI determine whether or not you get a spot after the interview, or just the interview? What I mean is, if my predicted UAI is, say, 98 (and I have a high enough UMAT score for a UAI of 98) I should get an...
