math

I'm not sure how to solve this one problem: "If α and β are roots of the equations x²+mx+n=0, find the roots of nx²+(2n-m²)x+n=0 in terms of α and β." I would really appreciate it if someone could show me how to do it. I'm like 9 weeks behind on work lol. Thanks in advance! :D

Hi all, I'm planning on doing mathematics extension 2 next term, im just wondering what I can do now to prepare for it, or even just some tips to survive the course. Regards

Hi! so I've decided recently to work on my math more and I thought I was improving but a recent topic test proved me wrong. While I can answer the questions within the textbook, I wasn't able to do so on my test. The questions seemed more confusing and I ended up getting completely lost. How...

I've been told that up to 30% of prelim content in maths is tested in HSC, but I was wondering if that 30% is kind of recovered/more so a foundation to concepts taught in year 12 or if prelim content is quite literally in the HSC?

Let P(x) = (x+1)(x-3)Q(x) + a(x+1) + b, where Q(x) is a polynomial and a and b are real numbers When P(x) is divisible by (x+1) the remainder is -11. When P(x) is divisible by (x-3) the remainder is 1. i) What is the value of b? ii) What is the remainder when P(x) is divided by (x+1)(x-3)...

I would be grateful for any ideas on this question :) , I know the use of the difference between cubes is used but how do you proceed from there?

Hi! I am offering 1-to-1 (and possibly small group) tuition in: -HSC and Year 11 Mathematics (Advanced, Extension 1 and 2) and Physics. Math and Science subjects for younger years. -Other high-school level Math and Physics e.g. A-levels, IB, Olympiads. -University level Math and Physics...

Any ideas? Solve cos^2theta - 5cos theta * sin theta + 6sin^2theta =0 between -pi ≤ theta ≤ pi

Hiya, I'm in year 11 and I'm kind of screwed. I'm doing extension 1 maths, advanced English, chemistry, biology, economics and modern history. So far, I'm not doing well. I'm atrocious with time management, and I procrastinate like there's no tomorrow when I'm stressed. I attend tutoring for...

My Maths extension 1 exam allows us to bring a cheat sheet with us. Is there any way I can exploit this advantage to make the test even easier for me or should i just write formulas etc?

I was wondering what is the best way to get rid of silly mistakes in maths, is it just repetition or is there a better way?

Hi, So I'm in year 12 (well in a week) but I'm so stressed about my math skills. 2020 has personally been a very tough year and probably the most difficult times I've encountered. As a result, I was very mentally and emotionally strained and found no motivation to study. Now, I'm trying to get...

TL;DR If you want to go into medicine; 1. take chemistry, and advanced math or higher 2. sit the UCAT 3. apply for early entry into the "Bachelors of Medicine/Bachelor of Surgery" (MBBS) at JCU and Curtin 4. if you don't get in, apply for regular UAC entry into any MBBS 5. if you don't get in...

Hi! I need help balancing an equation for my textbook questions and I have tried everything and I can’t seem to work it out. ‘Why is the following equation not balanced? Find the errors and correct them’ 3Co3+ + 2HPO42- Co3(PO4)2 + 2H+ thank you!

I have a question I need help with and I’m not sure on how to actually work it out. The question is ‘solutions A and B are labelled ‘0.15 M CaCl2’ and ‘0.25 M CaCl2’ respectively. Both solutions contain the same amount of CaCl2. If solution A has a volume of 50mL, what is the volume of solution...

I am thinking of joining Du but thru can't tell me the topics in the entrance exam (fair enough), but I don't know if it will be fair as in ONLY year 11 topics that would've been covered in school already or if they will put in accelerated stuff and maybe even year 12 questions (which I...

G’day fellow BoSers as the title suggests, is it worth doing math questions ahead of time from the class textbook of the teacher is eventually going to just assign us do those exercises? Would it be better to buy a separate book to self study and do the class textbook up to the normal speed...
