As a Math teacher I have been watching many Math videos mainly by Trinidadians and I love your videos! For some of the others there are errors and Students have to be so careful about which videos they watch! For some questions different videos have different answers!
Method 2 is broken up into abundance of parts which was easy for me.Btw Kerwin Springer,I passed for Vishnu Boys Hindu College and I am so grateful for your assistance.I used to do your tests before SEA and to my surprise I passed.
My brain isn't that complex in maths to even try to comprehend the natural method So I guess I maybe loosing one Mark and just going with the formular method... Slower, less intelligent ppl who's with me!!! ??! 😂😓😥
6:07 sir for the formula with the completed square on top you put (x - h)^2 but at the beginning it was (x + h)^2 so I'm a little confused nevermind, i commented before i saw in the video he corrected himself....mb
Idk if you ever solved this but multiply 1 by 12/12 to get 12/12 or find the LCM of 1 and 12. Then 12/12 - 25/12 = -13/12 or -1 and 1/12 if you know how to convert improper fraction to mixed.
In this instance, a whole (or 1) can be expressed as 12/12. So we could read the sum as 12/12 - 25/12 which would give us -13/12 when we convert that to a mixed number, it becomes -1 1/12
1 -25/12 change 1to12/12 then the values will be 12/12. -25/12. So I get 12-25 which is 13 that becomes 13/12 and change into mixed numbers you get 1 1/12
Great work sir. Can you please help me out on this question? In a group of 40 students, 28 play tennis and 22 play chess. What is the LEAST number of students who play both tennis and chess? (Options: 6, 10, 12, 18.)
Kerwin Springer Thank u. That’s what I use & I got 10. But I was wondering why do they say 'LEAST', isn't 6 smaller than 10? Is 10 the GREATEST or LEAST numbers of students who play both tennis and chess?
@@symplicity6835 the total is 40, but the player total is 50 that is to say, for it to be 40 people overall while still allowing the 28 people in tennis and 22 people in chess, 10 people need to overlap^between the two sports ofc it could be more than that, all 22 people who play chess could technically also play tennis we'd have no idea but no less than 10 people can play both, because if it were less then the total students would be over 40 no less = least
Hi, you keep saying quadratic equation, but it's not an equation without the equal sign. It's just a quadratic form. Of course, l know even though you say equation it will not change the answer. However, in math we should always use the proper expressions. Otherwise, a good video and explanations.
You're right. I often explain the difference between equation and expression in other videos. For the exam you will usually be given an equation. Years of saying equation in class got the better of me.

i have accepted losing 1 mark is better than whatever...that was
SAMEEE
This is quite a prickly topic, thanks a bunch
Thank you sir I have a test tomorrow good thing I found this video 👍

I'm just learning this natural formula thing and I tried it 4 times and.. its pretty easy
Can u explain solving quadratic equations using graphs?
And thanks for the video!
My brain isn't that complex in maths to even try to comprehend the natural method
So I guess I maybe loosing one Mark and just going with the formular method...
Slower, less intelligent ppl who's with me!!! ??! 😂😓😥
am with u 100%
good luck
let's do it lmao
Vatoya Soodat same here😭
Vatoya Soodat well i taught was i thinking only lol
Bro, again another excellent video. Never thought maths would be so fun:) Watching your videos from sunny London (UK). Stay safe everyone:)
I understand now thank you, thank you
me learning this the night before the exam...
thank you sir, continue the good work as technology is being improved
God bless you sir
Sir u could do the methods of surface are and curved surface area of the different shapes please, thanks
6:07 sir for the formula with the completed square on top you put (x - h)^2 but at the beginning it was (x + h)^2 so I'm a little confused
nevermind, i commented before i saw in the video he corrected himself....mb
sir I really love your channel you should have started from September
Alexsis Honyghan I only got the epiphany waking up one morning in January...
+Kerwin Springer lol epiphany should a come from September :-)
I don't understand the 1 take away 25 over 12 pare. How did you get 1 over 12
Idk if you ever solved this but multiply 1 by 12/12 to get 12/12 or find the LCM of 1 and 12. Then 12/12 - 25/12 = -13/12 or -1 and 1/12 if you know how to convert improper fraction to mixed.
thanks bro. this lesson was predominant
was wondering where it went.... thanks kerwin springer
Thank you so much, have a math test tdy
Great video Thanks alot!
Sir Springer, i was wondering how the 1-25/12 changed to -1 and 1/12
have to create the same dominator so you multiply the one by the 12
In this instance, a whole (or 1) can be expressed as 12/12. So we could read the sum as 12/12 - 25/12 which would give us -13/12 when we convert that to a mixed number, it becomes -1 1/12
how did you get -1 1/12
1 -25/12 change 1to12/12 then the values will be 12/12. -25/12. So I get 12-25 which is 13 that becomes 13/12 and change into mixed numbers you get 1 1/12
dont forget vectors tutorial pleaseee
Anelka King this then stats then vectors...
I think.
Think..??? loll ok sir
Love the explanation man
This helped me alot, keep the vidoes coming, princess town.
1. 3(x+1)^2 -14
quick movements not missing any videos
Lol if again
Sir Im gnna die....I cannot wrk it out in fractions..no matter hw hrd I try...😢
Sir I thought the vertex form formula was a(x-h)2 + k you have a(x + h)2 + k
1) 3(x+2x)2-29
2) 3(x2-4x)2-19
Am I correct?
Pretty Angel rewatch the video and try again
excellent, thank you soooo much!
Why was the edit done? The question had -5x. Why then should we change to a positive number?
What is you could reduce to whole numbers ? would you do it the same way?
How will we use the natural method in our everyday life?
my goat
2 3s and 1 1s did referal for maths and english
3(x+1)^2-2
Great work sir. Can you please help me out on this question?
In a group of 40 students, 28 play tennis and 22 play chess. What is the LEAST number of students who play both tennis and chess?
(Options: 6, 10, 12, 18.)
10
Use sets...
Kerwin Springer Thank u. That’s what I use & I got 10. But I was wondering why do they say 'LEAST', isn't 6 smaller than 10? Is 10 the GREATEST or LEAST numbers of students who play both tennis and chess?
@@symplicity6835 the total is 40, but the player total is 50
that is to say, for it to be 40 people overall while still allowing the 28 people in tennis and 22 people in chess, 10 people need to overlap^between the two sports
ofc it could be more than that, all 22 people who play chess could technically also play tennis we'd have no idea
but no less than 10 people can play both, because if it were less then the total students would be over 40
no less = least
you culd do a video on scales and maps pls
Great help to me
am I correct I got 1x and 2/3 for the jan15 so its 3(1x-2)+2/3 is it correct ??????????
100k soon 💯👀❤
I acustom seeing the work on a white board white paper
#1. 3(x+1)^2-5
#2. 3(x-2)^2-4
??
Sakile Williams correct
Brandon how did he get -1 1/12
Sakile Williams for the second equation I got
3(x - 2)^2 + 6
Shonnella Charles I can't explain through chat but rewatch the video and see if you the answer. I used a calculator and got 3(x - 5/6)^2 - 1 1/12
Shivani S Same
Thank you💪😌👌
Thanks for sharing! I posted a video on completing the square using remainder theorem. Let me know your opinion.
Wow this is epic
How did you get 1 1/12 ???? Help !!
Because in the calculator
Because in the calculator
Where did the -5/3 go?
Thanksssssssssss
That next equation is too much hard work😫
I good with my formula method
3(x+4)^2-6?
I have exam January 4th 2019. hmmmm not excited lol
Only problem in math is simple mistakes
sigh trig got me a way
