Wonderful explanation!! You covered everything.... I think it'll help me with my competition

Good stuff. Thank you 👍🔥

[@shafzkay1594]

is this for the new spec or old one. The content looks lyk the one for the new spec because im doing it but i dont know.

[@anansii9140]

this was so easy,, thank youu

[@bassic6959]

thanks for this vid very helpful

[@hamzahwaheed9528]

For solving the equations it's like solving a quadratic with +ve & -ve solutions but you don't square root anything.

[@iggyentertainment]

which app do you use to write like that? I want to make KZbin videos too

[@the2m736]

Thank you so much

[@khoanguyen-le4368]

when modulus is on both sides instead of squaring both sides is it not possible to just make the whole of one side negative to find one value and then do both sides as positive to find the second value ? You get the same answer as squaring and it is much faster

[@crazyplatypus778]

That's a property of modulus

[@crazyplatypus778]

If |x| = |y| then, x = y and x = -y.

[@sadanikadayarathna4735]

thx very much

[@mr.random632]

Don't you have to find turning point for quadratic graphs and make that positive too?

[@thiagodetm2564]

clear explanations

[@dennishamilton8009]

Not to sound rude but what is the purpose for having a Modulus function? What application would this be used for, both in maths and the physical world?

[@crazyplatypus778]

Just to pass the time....skip it bro

[@Manananana-pq2zk]

If u put it that way, I mean physical world there really isn’t any function that’s gonna help u LOL. Except for add,sub,multi,div functions there really is no use of it funny but ur future depends on it

When did this stop being called absolute value?

[@dhanyapandey8830]

16:53 why is it squared?

[@imhuman4213]

3:57 How do you know y =1 and x=0 on

[@mingyu1211]

If you’ve done linear graphing, you’ll notice that in every equation, you can find the y-intercept, or in most equations. For example: y = 3x + 3 That ‘+ 3’ at the end of the equation is the y-intercept, right? To work out the x-intercept, we make y equal to 0, and solve the equation from there; x-intercept in y = 3x + 3 would be, 0 (make y=0) = 3x + 3 then, subtract 3 from both sides (to get rid of the ‘+ 3’ of course😁), and you’re left with -3 = 3x And finally, x = -1 So, the x-intercept in y = 3x + 3 would be (-1, 0) on the graph! In summary, this youtuber has used the x & y-intercept method to draw the linear line; (sorry for the use of slashes instead of ABS bracketsㅠㅡㅠ) y = /2x + 1/ can be solved using the methods at 3:57 like this Hopefully I was able to answer your question...

This one is a level

[@demar3258]

Maths Genie Oh okay thank u sir

[@kuokhao5182]

hi, you made an error at 10:24 the x coords are supposed to be 3,-2 instead of what you put and y should be -6

[@ProPlayerGamez]

How is it an error. He has done it right

[@drgnyt7487]

@koukhao sry mate ur wrong

[@drgnyt7487]

dw i see why you think it is that though, you have to switch the signs to get the coordinates

Your explanation is very clear but in the conclusion you sure made a mistake It was supposed to be +2 and-4 not-2 and-4
