Need Help With A* GCSE Question ?

Nitefly · 6 Nov 2010 at 17:07

To answer these questions, work out Y in terms of X, or vice versa, and simply substitute that into the quadratic equation.

It's very methodical once you understand the process of what you are doing.

I was surprised I remembered it tbh, quite impressed with myself.

Best of all, about 99% of the people who answered the question in the exam will probably never use that knowledge practically in their lives

I could only ever do the first algebra question on the page. The rest of them I had no clue and the marks for the page in total were 25. Not fun. Now I don't know how to do any.

OP, do you understand it yet? If not, I'll write out an explanation for you if you want

It still is, so right back at ya

yep, still an easy question.

I think OP has just mixed up 'I can't do it' with 'insanely hard'.
But understandable - maths (for me at least) always seems completely impossible until you realise what you need to do, and then suddenly it's all super easy, and you wonder how you failed to understand it to start with.

Half the maths I was taught at school I do not use in my life at all, (I work as an accountant). Personally I think you should only be taught practical maths, what people use in everyday or work related. (of course you need a general understanding)

I'd have to disagree with your post. Your idea of 'practical maths' would constitute a career in accountancy. Of course you didn't use all the maths you were taught at school in your career. Maths is such a broad subject and compliments other subjects (eg: physics) very well.

For you, doing a mechanics module in maths might not be very useful, but for the architect or physicist it will be. For these people, doing statistics won't really help them that much.

All maths is useful in some area of everyday work

It may as well be swahili for how much sense that made to me.

That's incredibly worrying actually.

It's not really. It's only easy when you do maths or have been taught how to do maths.
