Been watching your videos for months, and they are enormously helpful. Thank you so, so much! Any horrible messages you get are just from people who are jealous of your outstanding work. Well done! :)
@xKAS11Mx its -25 as when you look at the equation, you dont have a +25 in there, theres only x^2 and a 10x, but if you expand (x+5)^2, you get an x^2 ( good) two 5x's ( add to make 10x, good) yet we get 5^2, or 25, which is not in the original equation. So to make the brackets true to the equation, we have to remove the extra 25 weve made by putting it into brackets.
Thank you, thank you, thank you. It has taken me the best part of a day to fathom this process from my poxy Open Uni books, to no avail. I've watched your video twice, and I've got the concept and have aced the assignment question. You're a gentleman and are up there with the Khan Academy.
Thank you alot for your amazing work. I appreciate you helping us,the students,out.We can all see how much effort you are putting into your work as well as your dedication.
You saved my life. I literally gave up on maths so close to dropping it but now I feel confident in lessons because I understand how to do it. Thanks your an angel
@theperformingguy112 Of course you can but I prefer to use this version as it seems easier to understand why it works and you dont have so much formulae to remember.
@Menacin you just use the formula. x^2 +y^2 +2gx +2fy +c where centre point is (-g,-f) and radius is (g^2 +f^2-c)^1/2 i personaly think his method is a bit wierd. ^ means to the power of if you dont know.
Thank you so much! i finally understand the concept. God bless you and keep up the good work you're doing. I'm sure many people appreciate your work :)
Hi, Im sorry if this has been asked before, but what software do you use? Thank you very much for your videos, i learn more in watching your videos for a week than a year of tuition.
Thanks, your videos explain these concepts in a concise and simply way. Really useful as I was at a blank and had completely forgotten how to do this :D.
Felt so intelligent when I figured out how this linked to completing the square with the C1 explanation. Thanks a trillion, gotta out do the other guy :D.
Thank you so much for the video! Would you mind letting me know how to do this qn too? The points A,B,C have coordinates (2,1) ,(b,3) and (5,5). Find b where b>3,and triangle ABC is 90 degree; right angled triangle
simpler way (minus)half the co-efficient of x (minus)half the co -efficient of y that will get u the centre for example (-5,6)-centre radius- square root (-5)squared + (6)squared - the constant (which is 9 in that question) put all that last step in calculator
hiya, I'm just wondering will It be right if you say that : If you half the co-effient of the x (+10) and change the sign and do the same for the y (-12), you'll get the right answer every-time, as it works in this example? (-5.6)
+Meg Gahan Yes, if it is in the correct form x^2 + y^2 + ax + by +c = 0. However, i would encourage you to understand why it works rather than use that method.
ExamSolutions Do u always subtract the constant when u complete the square? What if the one inside is not simply x like it's 2x? Shouldn't you multiply that with the constant you're going to subtract?
This channel is a lifesaver
@DextersChick because a circle with centre (a,b) has the form (x-a)^2+(y-b)^2=r^2 so -a = 5 so a = -5 and -b =-6 so b = 6
Thank you man your the reason why TH-cam is so amazing

Good luck. Glad to hear that the video helped.
These videos never age. Best on YT.
Pleased to hear that they have helped
thx
Greetings from the UK.
You saved my life. I literally gave up on maths so close to dropping it but now I feel confident in lessons because I understand how to do it. Thanks your an angel
+xoxojanoskianator66 Another life saved. I hope you can go from strength to strength now. Good luck.
Same here!
I have a math final tomarrow and that just made my grade Thanks and keep it up!!!
Saved the day at 1am in the morning
just blew my mind on seeing how easy it is..those colors helped so much.. thanks
@theperformingguy112 Of course you can but I prefer to use this version as it seems easier to understand why it works and you dont have so much formulae to remember.
Greetings from Singapore!!!! Great tutorial, as over here this topic is included in the GCSE
thank you, you made it so easy to understand.!!!!!!!!!!!
Great vid, you're the best at explaining thanks allot!
@Menacin
you just use the formula. x^2 +y^2 +2gx +2fy +c where centre point is (-g,-f) and radius is (g^2 +f^2-c)^1/2

Thank you so much! i finally understand the concept. God bless you and keep up the good work you're doing. I'm sure many people appreciate your work :)
@chardog19 Yes but that is why I then subtract 25 and 36 so as to equal the line above.
Hi, Im sorry if this has been asked before, but what software do you use? Thank you very much for your videos, i learn more in watching your videos for a week than a year of tuition.
This presentation is really helping me to find the tangent easily.
oohh...so that's how easy it was!
you've explained this so easily. ive been struggling to complete the square but now im confident in doing so. many thanks!
Well done.
Thanks, your videos explain these concepts in a concise and simply way. Really useful as I was at a blank and had completely forgotten how to do this :D.
Superior explanation compared to my teachers. Would have failed if it weren't for this. Thank you so much! :D
basic squaring of a bracket :(x-3)(x-3)=x^2-3x-3x+9
Great video thanks!
Thank you so much, your tutorials have helped me so much. and improved my maths skills.
Super helpful, thank you!
Thank you
cheerz, lost the disc for my edexcel book, needed this explaining cheerz m8, youve just gotten me an A XD
@standingpretty Thanks
Way better than my teacher taught.
Thank you!
Speed this up to x1.5 and best maths video made
@bistoha Hope so - thanks
Helpful
thank you
@ilasttt Well done
@100flobby Thanks - the website gives more though
Felt so intelligent when I figured out how this linked to completing the square with the C1 explanation.
Thanks a trillion, gotta out do the other guy :D.
+pokerockman Go for it.
Thnx really needed it :):)
thanks :) so simple and well explained :)
Thank you for this awesome vids! :D ☺
Thank you so much for the video! Would you mind letting me know how to do this qn too?
The points A,B,C have coordinates (2,1) ,(b,3) and (5,5). Find b where b>3,and triangle ABC is 90 degree; right angled triangle
Hi Michelle, we don't answer questions that don't relate specifically to the video.
thank u so much
thanks
@Peacock2613 Well done
simpler way
(minus)half the co-efficient of x
(minus)half the co -efficient of y
that will get u the centre
for example (-5,6)-centre
radius- square root (-5)squared + (6)squared - the constant (which is 9 in that question)
put all that last step in calculator
thanks a lot for this video.
🙂
Do we get this in Cambridge exam A level
What should I do if I want to use this formula xx,+yy,+g(x+x,)+f(y+y,)+c is equal to zero to find the equation of the tangent
That's ok
i just don't get one thing, when u removed the brackets (x-3) squared, why did -3 become -6X, shouldn't it become +9 ????
interesting concept but cant you just use the formula. x^2 +y^2 +2gx +2fy +c where centre point is (-g,-f) and radius is (g^2 +f^2-c)^1/2
hiya, I'm just wondering will It be right if you say that : If you half the co-effient of the x (+10) and change the sign and do the same for the y (-12), you'll get the right answer every-time, as it works in this example? (-5.6)

It is so easy
Thanks - This is the English way not the American.
then whats the american way and why bro
@ZtifEons Cool
Ty that helped
U waffled a lot though with the rearranging. That was annoying😂
Oh well, can't win them all.
@DDrogba113 Thanks
Chech out the video ' How to use the Radius Ruler" on youtube.
@avn2sh only revenue from advertising
how does it go from (x+5) (y-6) to -5 and +6?? been trying to reason this for ages and can't figure it out , someone help me!
x+5=0 therefore x=-5
y-6=0 therefore y=6
equate them to zero
i love you
It is MATH (singular), there are not two! We don't say sciences or englishs. Come one, Brits
Eric Hanaway on*
it's a simplification of MATHematicS mate
makes no sense why you'd leave the 's' in but hey I ain't gonna question it
British English = Maths and American English = Math. Both are correct.
Thanks
Thank you!!
Thankyou !
No probs. Thank you for your support.
