AS & A Level Maths No. 4. Equations- from www.mathstutor.biz

@mathstutorbiz

i get how to all of these kind of questions but the questions im getting is alot diffrent like

3a-b=11

2a+b=9

[mathstutorbiz]

Please read previous comment: Yes this method of "squaring out the brackets" will always work. "Square the first term, double first term multiply by second term and lastly square the second term"....... So "and then multiply by the second term" which may or may not be a 3..... most likely not!! Have another view and listen to the video. mathstutor

[p6subhrap]

when you double the dirst term(8), then multiply it by the 3, does that work for all equations? thankyou!

[OSBUK]

Sir, I'm confused about a small thing: On the last question, when you substitute x=3 into 3x+y-8=0 you get y=-1, but if you substitute x=3 into the other equation y^2+3x^2=28 you get y=+1. Please help.

Thank you! I am actually doing my AS levels in Mathematics and didn't quite understand my textbooks explanations for this method. Much appreciated.

[MrHaddify]

Thank you so much can not tell you how much that helps however this question can also pop up i the GCSE papers which is what i am going to do soon gunna revise my head off tomorrow!

where 48 came from ????????????/:(

[mathstutorbiz]

@AfghanStar4ever Please have another listen, (16 x 3 =48) but where did the 16 come from,,,,,,, you need to understand the "quick" or "short" way to expand brackets.

Have another listen. mathstutor

[Yu2Kal]

Well if your can't do these your obviously not working at the A level mathematics standard, even though it is so easy...

[SowdenLFC]

You sound like a massive twat, and you are. Go outside you hermit.

[Yu2Kal]

Yea ok, atleast im not thick

[SowdenLFC]

wtf? you dont realise how much of a dirk you really are? Im thick cus i cant do equations? :S lol dickhead

[Yu2Kal]

Sorry GANGSTA!

[spider49]

does the quick way of solving quadratics at 6:30 always work?

thanks

[mathstutorbiz]

Yes this method of "squaring out the brackets" will always work. "Square the first term, double first term multiply by second term and lastly square the second term"

[lamfsc]

Only if you are careful with the positive and negative signs. I really think that pupils studying A-level would see this as a very basic skill.

[tobytran]

Thank you very much for your videos they are helping me no end :D. You explain things much better than my actual teacher. Thanks!

[Lollinastar]

CIAOOOOO

[shonnydee]

eeeeezzzzzzzzz but can be dun much easier

[craigcranefists]

agreed but it still helped me in my exam

[4EVAORLANDO]

its AS & A2

[cactus91]

at wad age does students in the europe learn this?

[samioni]

difficult to answer..... it depends on ability. The more able would come across linear simultaneous equations age 12/13 (ish)on the Key stage 3 exam. Most will meet linear simultaneous equations 15/16 years old in GCSE. The simultaneous equations with a quadratic appear in AS/A level GCE, student age "around" 17 years old..... but it does depend on individuals ability. Hope this helps. All the best. mathstutor.
