Hey, TGMT I just wanted to let you know your videos are really amazing and helpful for GCSE students trying to revise for upcoming exams, I have my Math IGCSE in January (almost 2 months away) and i'm using your videos as a way to revise previous topics and it's always been helpful and always works. Thank you sir for providing these videos. :)
That’s amazing! Thank you so much for the kind words I’m so glad my channel is useful for your exam preparations! Please do let me know how you get on 😁🙏🏼
Last year I would use just old revision text books to revise and got a 3, with your videos i managed to get a grade 7 and hope for an 8 maybe in my actual ones. Thank you so much for your effort and clear explaination. Only Maths TH-camr i can watch. 😂 🙌🏻
@@adzyt9185 What I would do is print out your specification (edexcel or aqa.. etc) and make sure its the updated version for 2022 as they tell us whats gonna be on our assessment. I would definitely go through this guy’s videos and highlight the topics on the specification as you go on. Once you have highlighted all of it go on to maths genie and do all the past papers. And keep doing that until the summer exams. I highly recommend this as gcse maths papers each year are basically the same question just with different numbers and worded differently. If i can get from a 3 to a 7 im sure you can. Good Luck!!
@@TheGCSEMathsTutor I finished maths offically today and would just like to say a massive thanks for helping me through maths. Me and maths weren’t always on the same boat but I have been watching you since the summer 2021 and I must say I do see maths in a different light. Thank you for getting me to where I am and although I will not be taking maths in A-level it was an enjoyable ride to say the least, wish all the best and once again thank you for not just saving me but for saving so many year 11 students nationally!!
Thank you so much for these videos, I have always struggled with maths but your videos have given me so much confidence. I always used to say that I " hate maths " but now it is one of my favourite subjects, Thank you !
Thank you so much, I am a grade 9 student in maths, yet I still couldn't get turning point questions around my head. However, with your clear explanation, you helped me understand everything with ease. Thanks a lot for this
@@sukiestar8401 aaaaah perfect, here’s the link for that: th-cam.com/video/ugcR-khcTLQ/w-d-xo.html just incase you hadn’t already found it! Let me know how you get on! 😁🙏🏼
12:27 -7 1/4 x 2 = +14 1/2, two negatives give a positive, you should write it with brackets instead as -(7 1/4) x 2 to get -14 1/2 otherwise it's confusing because I don't know what you mean unless you explicitly say it
For turning points, can i differentiate? If it doesn’t ask me to write it in the form (x-a)…? because we learnt it in further maths and it’s much easier
Might be worth a mention that the reason the turning point is as it is shown is that the bracket is at its minimum (i.e. zero since it's squared) when the x is the opposite of the number and hence y is at it's lowest value, i.e. the turning point. The 3 rd example has no real roots which is why the y value of the turning point is above the x line, i.e. +8
7:49 I understand that the first turning point is positive 1.5 because there is negative 3/2 inside the bracket and we change the signs. What I don't understand is WHY we change the signs and what exactly does the coordinates do? An explanation would be helpful really.
We change the signs to make the equation equal zero, because they cancel one another out. The co-ordinates plot the points of a line on a quadratic graph where they intercept the axes.
@@magpiestudent9357 "Intercept the axes" ??? No "Turning Point" (also called Vertex in posh maths) is the bottom of the U shaped graph if the x squared was positive or if the x squared was a negative then the graph is upside down (kind of like a big frown) and the turning point is the single highest x,y co-ordinate at the top of the graph. Isn't that it?
Like most gifted mathematicians unfortunately you make too many logic leaps in your explanations without explaining why you have made that step. I am sure that Most of the time you don’t even realise you are doing it because to you the next step seems obvious, however the video is mainly going to be watched by students who by definition, don’t understand the concept fully and therefore need someone to provide a better explanation than they have had so far at school.
Meerkat King What aspect of identities? An identity is simply an equality relating one mathematical expression to another, such as 2x + 5x = 3x + 4x 😁🙏🏼
Meerkat King To be honest there are very few examples that aren’t already covered through these video, you could be asked to show that ax^2 + bc + c = (x + d)^2 + e for example just by completing the square to show they are equivalent but there is nothing that I haven’t already covered, unless you have a specific example?
Meerkat King In this video I cover the skill you need for this, completing the square with coefficients greater than one: th-cam.com/video/7kuQL6lV8II/w-d-xo.html For this question you need to first complete the square: 2(x^2-10x+c/2) 2((x-5)^2 -25+c/2) 2(x-5)^2 -50 + c From there you can see that b=5 so 3b=15 If 3b = 15 then -50+c has to equal 15 So c=65 😁🙏🏼
for the very last q, at 13:13, isnt it -8 1/4 instead of -6 1/4??? i keep redoing the question and suspect that i'm slowly going crazy with all this math, no offense. sighh i need a break
Emmanuel kalumba 90% of the topics can appear on paper 1, with the exception of a few like iterations and using a calculator! There are very few topics that can’t appear on paper 1 😁🙏🏼
(x+4)^2 is the only squared bracket that can give you +8x in the quadratic so this must be used! When you expand (x+4)^2 you get x^2+8x+16 so in order to balance it out you just have to complete the squared bracket! Not sure if that is helpful? 🙏🏼🙏🏼
? what explanation do you need for that, it's just x^2 + nx + k, you take x^2 + nx to make a form like (a+b)^2 and then minus the thing you've added to make that square brackets. simple as that

Can you write the coordinates as (2.5, -4.5) at 10:00 ?

thank you! this was really helpful as i never really understood how to do it
Could you please explain at 11:13 why we need to take away 1/4 rather than 2 1/4
because we only need the number two, so taking away 1/4 from 2 and 1/4 would leave us with 2 by itself
What happens when the coefficient of x2 cannot be facotirised with the constant?
Then the other numbers becomes fractions/decimals and it gets very complicated! 😰
This helped so much! Thank you🥳
Thank you for this !
8:17 can I just divide the entire equatio by 2?
wow i learned so much from this
Really Helped!
Thank you so much sir!
No problem at all 😁🙏🏼
Very good sir good job nice work!!
Thanks for sharing! I posted a video on completing the square using remainder theorem. Let me know what you think.
Would this question come up on a calculator paper or non-calculator.
It could be either 😁🙏🏼

@@paulcazza I see, thanks.
great video so helpful
why did you flip the sign to positive 4 for the second example?
number inside the bracket changes sign
Goat
at 9:33 why do we not expand the bracket? why does it stay 2(x-5/2) and not 2x-5??
thank you 😊
thank you
Thanks
My pleasure 😁
is this the same concept as differenciation?
I have a question! Why do you flip the sign on the x when finding a turning point? Thanks :)
because that whole bracket needs to equal 0 after squares as that’s the lowest possible value (a negative squared is a positive)
@@bigfatL thankyou:)
thank you for ending my struggle
Hi there Gcse maths tutor could you write your wander in decimals instead of fraction
when squaring the number from the bracket do u always have to turn it in to a mixed number?
no, leaving it improper is still fine
Could it be possible if you do a video like this but on geometry?
Which elements of geometry? 😁
The GCSE Maths Tutor circle theorems and more of the harder topics in geometry
火Cursed consider it done 👍🏼
GCSE 2022’ where you guys at!!
Does it matter whether your answer is as a fraction or as whole numbers?
no
10:10 so what happens with the 2 outside the bracket ?
U leave it
Your just a genius I’ll be so honest 😹😹😹
Haha thank you!!
May I ask why do we flip the sign to make it positive?
bc the euqation equals to zero
its like yk how u flip it when ur doing quadratic formula yeah

This!!! I am left so confused with half the stuff he does like he’s assuming I alr have a degree in maths whilst I’m watching these gcse videos
U problem

For this question you need to first complete the square:
2(x^2-10x+c/2)
2((x-5)^2 -25+c/2)
2(x-5)^2 -50 + c
From there you can see that b=5 so 3b=15
