I like how you gave a real life example of how to find the x & y co-ordinates of a line that cuts a circle. Very clear explanation for a parent who left school 30+ years ago.
I did not go far with math in high school, I got algebra, some geometry, and that's all. It's been 4 years since my last math class and i'm going to be taking a college placement test soon. Your way of explaining things and your teachings make it easy to understand it, the first time. Thank you much!
Very helpful! Thank you. Although there could be an improvement as I had a good understanding of what you were talking about, and the fast pace and skipped steps were fine, but If I didn't have the prior knowledge I feel it would have been very hard to follow. Anyway good vid, Cheers mate
I love you so much... i've never been taught this but was given a similar question...i saw your similar video to this and i understood instantly then i came across this one and tried to solve it myself before the video started and i got it...thank you so much you are really helpful.
Hi - you can only work out X if the equation is equal to something. In your example, if you made it equal to 3, you’d get: 5x(x + 4) = 3 Expand to 5xsquared + 20x = 3 Or 5xsquared + 20x - 3 = 0 You could then use the quadratic formula to find out if x has any values. Hope this helps and all best S
hey, this video was very helpful thank you! i just have a question for one of my tests and i tried to look every were but still cant find an answer. the question is 2p^2 - p = 15. i know p=3 because i worked it out kind of guessing but i want to know how you would come to an answer like this in case i have questions with higher numbers. I know that p is three but can one of you guys tell me without being smart -so it is easy for my to understand- how to do it?
Hi - Glad the video helped. Here's a link to a playlist that might be useful ... I've also added a video with your specific question: ruclips.net/p/PLPglScc3TJ-Ov7F1_VRLUQ7Ecf5PrQ-T3. Hope it helps and all best S
Hi, can you please check if i done it correctly or not, when i factorised i didn't divide by 2, thank you a lot, 2x^2+6x-20=0 -40 and 6 (x+10)(x-4)=0 X= -10 x= 4 y=3+x y=3+(-10) y= -7 y=3+x y=3+4 y= 7 (-10,-7) (4,7)
Man your videos are always super easy to follow! Revising physics and some algebra for uni and I stumbled upon this. I always wonder what math is used for... especially this... what can be substitution used for? Like in real life, could it be used for something? Figuring out something? Physics? Engineering? Tougher equations? It bothered me that in high school we just learned things to learn things but never really got an answer what these equations could be used for or what's the point of learning them. Could you give me an answer good sir?
Hi - thanks for this and completely appreciate your comment. Personally I see maths through Engineering due to my previous career ... for me, most maths was very real. I could see how important it was to understand the effects of mass, gravity, momentum, force, friction, heat etc - maths is really just the language we use to describe these things. High School maths tends to provide a basic foundation; depending on your career, it might become less or more important. Either way it's great that you're asking the questions 🙂 Here's a post on my site that might be of interest: www.3minutemaths.co.uk/what-use-is-a-quadratic-equation/ Best S
sir can you do a video on completing the square please and similar shapes when you need to work out a side of a shape that looks identical to another for example you have 2 cylinders that are identical you are given 1 cylinder that has enlarged sides and the others small and you need to work out n (Unknown) bit of a mouth full i know sorry.
+BanterComedy - Hi - here's a vid on completing the square ruclips.net/video/73d9Xpl96T4/видео.html and I'll look into similar shapes and let you know when done. All best S :-)
can you do the part you did with x with y , i cant re arrange the equation to make it y = so therefore are left to substitute the y into the x squared instead of the x into the y squared
MorganFxrmer Yes, you could, either way will work. Here’s another example How to work with simultaneous equations - eliminating x ruclips.net/video/J_b4yIMUiSw/видео.html. Best S
You saved my life!!!!!!!!!!!!! Well explained. First time that I do this equation and I could come up with the result, thanks this video :) . Thank you so much!!!!
Shouldn't the second coordinate be (-2, -1) as I thought when x = -2, substitute into the equation y = 3 + (-2); y should be -1? Correct me if I'm wrong. Thanks for this video though!
Hi - At the moment I don't tend to offer online tutoring, although might in the future. I do have a website though www.3minutemaths.co.uk. All best S :-)
Toffee Munch I’ve just completed this question , when you get down the the simplest form of the equation, use the quadratic formula to find 2 values of x then insert them back into the original to solve for y
Thanks Simon, I understood everything, though it might have been helpful to mention that (a.c) should add up to (b) while factorising.... and perhaps to correct the circle graph.
You're more helpful than my actual maths teacher but I still want to cry in a corner cause it's maths😢

Literally same, maths is so hard!
at least its not english, english is hell and torture
You explain slowly, that is very helpful to struggling learners.
Your explanation is simple, 100% easy to understand. Great work!

(x+y)² = x²+y²+2xy
You can use this formula too for finding it.
thank you this was very quick and simple and i understood easily
That’s great and glad to help - all very best S :-)
"You might wanna slow the video down a little bit" Nah i increased it to 1.25 so its much better
SAME
I increased to 2x
you are really good in the explanation and solving.i'm ready to learn a lot from you, and i love to be better than you.
Like your teaching Simon! easy substitution approach!
Glad to help and all best S :-)
Good explanation . thanks all the way from South Africa
Thank you Thank you Finally someone i can understand no waffle what so ever*
How would you determine x if when you factorise it, it is like this: 5x(x+4) for example. Great video though!
Hi - you can only work out X if the equation is equal to something. In your example, if you made it equal to 3, you’d get:
5x(x + 4) = 3
Expand to
5xsquared + 20x = 3
Or
5xsquared + 20x - 3 = 0
You could then use the quadratic formula to find out if x has any values.
Hope this helps and all best S

very helpful for a gcse further maths student, thank you :)
Hi, can you please check if i done it correctly or not,
when i factorised i didn't divide by 2, thank you a lot,
2x^2+6x-20=0

Simon Deacon, PLease can you tell me how sometimes when you factorise and there is a coefficient before a^2 how it equals a fraction?
Hi - no prob, although please can you give me an example? Best S :-)
You saved my life!!!!!!!!!!!!! Well explained. First time that I do this equation and I could come up with the result, thanks this video :) . Thank you so much!!!!
How would I present my answer to a question of this type on an exam paper?
please explain x^2 + y^2 = 64 and y = x + 4.... whenever i get to the factorising stage i don't know what to do, it doesn't work!

Really helpful, thanks!
better than Hegarty maths
But 2x^2 +6x-20 is 2(x+5)(x-2) , so wouldn't the answer to x be different?
Lol, my reply is a bit late haha but I got the same answer as him so I think your method is incorrect.
Ya that's what I was thinking coz like he divided by 2 but then I'm sure you have to show it tho
Shouldn't the second coordinate be (-2, -1) as I thought when x = -2, substitute into the equation y = 3 + (-2); y should be -1? Correct me if I'm wrong. Thanks for this video though!

how do you solve x^2 + y2 = 11? i can'y find the video anywhere

Solve algebraically the simultaneous equations x squared + y squared = 25
