At 6:15 it was supposed to be -4b instead of -4y
at 7:02 it was supposed to be: 14x² +28X-6X-12
Sam M thank god bc that's what I got
Sam M thank you. I'm feeling stupid over here lol
Sam M that's what I thought, ok thanks
Thanks
I knew it
Sam M thank you I thought I was wrong but now I know I’m not
when your teacher can't teach you simple algebra so you do it at home instead fml
Ah, you in your garage again, I see.
Polo new job
clear that's me right now
Trash af
clear I know!!!
Its disappointing that a 12 minute video can teach me something that takes the school multiple sessions to teach the class...
saaaaaadddd
I agree
true, i know.
even though this is from ages ago you should stfu, there's students out there that try their best even if math isn't their strongest subject
IKR LIKE WHYYYYYYYY
calm down people, if you make lots of videos, you are prone to make mistakes...thank you so much for your videos. I learn a lot :)
-b x 4 does on equal -4y. It's -4b ?
That's what I was thinking
+Ben Fox same here!! its 4b
+ZimFab I got so confused when he said y
calm down guys he made a mistake
Alta Willemse can use your own noggin too
Who else was shouting
ITS A B!!!!
tHeRe'S a BeE?!
I'd toss my book at u if u were in the class with me 😂😂😂 jkjk
I love how after watching a 12min video I feel more ready for my test tomorrow than the hours I spend in actual school.
Ikr my teacher is so bad at explaining!!!
Me rn
this guys voice is like liquid chocolate
Would love to see the face behind the narrator! ;-)

monsterjazzlicks it's sazzy from big Les show
ROLOTHESTORM #ROLOTHESTORMINGIT
Well I emailed him with some questions and also made a donation, but I don't think he must be bothering with checking/updating his channel anymore?!
monsterjazzlicks yeah not sure pal, but not gonna lie his stuff is better than any maths teacher I've ever had
Never thought I would find maths fun until now 😬
Ive just started my optics course and my maths was shocking. you have seriously helped me out alot !! thanks !!! !
I have learnt more through this video than attempting these for many months at school, you are a maths hero!
This video has been more help than my whole maths classes
U made it soooo much easy for me tk u man
Thanks bro you´re better than my math teacher.
Guys he said 2x * 7x= 14x I thought I would be 14x squared
+Ben Fox i think he just missed it.
Yes it is 14x squared this guy is just a dumbass don't learn from him!!!!!!!!!!!
Slayzer dude don't say that his other videos are great. People make mistakes and you can't judge them for making a mistake once.
Yea
@ 7:30 - '+14x' and '+22x' are both LIKE TERMS!?
ay+4a-by-4b not 4y
U help pass my gcse thank u vvv much last year
SERIOUSLY IF I FAILED MY MATH PAPER THIS VIDEO IS RESPONSIBLE FOR IT
7:49 nice voice crack, thanks for the video even though its 6 years later
Lo u watching it in 2019 too?!🤣✌
Almost 2021
In 2021
Half way through 2021 fml
Yeah cause the answer to (a-b)(y+4) isn't ay+4a-by-4y
the answer is ay+4a-by-4b
DIMPLES6224 i totally understand
Thanks I was rather puzzled with his answer
+DIMPLES6224 thx for a second i got it wrong
thought i got it wrong
Wow just brushing up on my skills and pretty darn happy I caught that immediately! Oh well, it was a simple mistake when your going that fast! I am just pleased with myself!!! Lol
I think you made are a few mistakes in this because 7x times 2x is 14x² and not 14x, but thanks anyway... :-)
Yeah,I just did it and I say wtf?XD
I caught that one too! We are on it :)~ YeaA I love math!!
U are right
Love you sir
Mate ur a genius, you have helped me with maths sooo much thanks a lot!!!
Helped with Homework!
I find all your math cool
So easy to understand
Great help as we are heading to do our GCSE
This guy is a god!
Thanks for the help.
Cheers mate, wish u were my teacher
Your voice is super relaxing
First thanks for this lesson. Secondly don't you need to add 14x and 22x together? I mean 14x+22x = 36x? Thanks once more.
here (a+b)(c+d) =ac+ad+bc+bd right??
+JoVaNsLaYeR
Yep, that's correct
holly crap! i paused the ad when it was 14 seconds till it ends! (the Uni one) And the guy looks so bloody freaky! ok but yeah thank you this helped heaps
have a placement test tomorrow he has told me im already going to make it in to the highest class. I still want a good mark!
wen i listen to a person tlking and they hav a cold for some reason it brings tears to my eyes and the next day i get a cold
very thankful to u i understood expanding bracket thanks
Just use foil it’s much more simpler
First
Outside
Inside
Last
Thank you for tips
thx u helped me 4 my cat test 2day
this was very understanding . thank u
yes ur right zakaria
you sound like the great white from finding nemo
Bruce's voice actor
Really help me
Great video. Thank-you so much
I have a question on (7x-3)(2x+4) it would be 14xsquared +22x-12 right
Never mind literally the comment right before mine answers it
3:36 isn't it, 5x^2, and also 6:10 why Is -b x 4 = 4y wouldn't it be 4b
@ 6:10 I think it should be: 'minus 4b'.
it's 5x. you're not multiplying you're adding. if x are apples, 2 apples plus 3 apples is just 5 apples. only in multiplication that you get 5x^2
FIFA Lords & Legends You mean not @ 6:10?
X-Factor Gaming wtf?!
yea bro same hear
so so helpful thank you 🙏
if u r the coolest chicken, can i eat u
Cheers
this is very helpful thank you
Thank you soo much
This was so helpful !
think you got the answer wrong. should say 14x² +22x-12
Thanks mate
On the problem ( a-b) (y+4) shouldn't it be ay+4a-by-4b instead of -4y at the end??
thx for helping me m8
Another mistake @ 7:00 you wrote 14x it was supposed to be 14x with 2 on top of the x :) thnx man love your vids ;)
cheers mate
what is the software program you use?
thank very much
how could -b * 4 = -4y
from where did the y come out
Its wrong it should be -B * 4 = -4B
my prob he's stupid i got 9 over 10.....
+Tecmath - do you have the LINK for the next chronological tutorial please? Thanks.
Just thought i should add- you could use 'FOIL' - First , Outside, Inside and Last. Its very useful and easy to remember.
Thanks alot for your help I really needed it. I've just subscribed and I hope more videos will come soon
isnt 7x X 2x 14x squared?
No beacuse when it’s letter and number the same like this for example 4y+7y =11y it’s only squared when it’s like this 5x +x equals 5x squared I think u get it now?
@@subanjama5267 I've graduated now but thanks man!
This helped so much 😅😅
Thankyou so much!
Ty, just saved my life XD
It's better than the grid method
Thank you ❤️
What if the brackets were being added together though. Like this:
([S-V]/T) + ([S+V]*R) = P
P=400
R=0.0005
V=14,000
T=36
S=?
How do I rearrange the formula to find "S"?
I really like your video because in my class it helped me get all my works right 😀
Very helpful and What white board do you use???
Thanks to you im the smartest girl in my class ; )
thanks.
I think you caught the 3rd equation wrong, (a-b)(y+4)= ay+4a-by-4b Not>> ay+4a-by-4y...And there are more mistakes...but thanks anyway it was really helpful..
Best, and clearest explanation I have seen. Thank you.
Thank you Sir for this video explaining how to expand binomials,since I was a little confused at first. Hope you have a nice day :)
As already stated in another comment, there were a couple of written errors which could have easily been corrected by editing the text in post-production. It is a shame as it is a really well explained video but these errors could confuse people that are new to expanding binomials.
What program did you use?
it looks like powerpoint
he will have paused the video to change the pen colour
at 5:04 instead of adding -x and -8x why cant we subtract -x from 2x^2?
Shouldn't it be 14x² instead of 14..?
Ur much better than miss mckendry
(a-b)(y+4)
ay+4a-by-4B
you got it wrong sir if we do B×4= 4B you got 4Y idk why?
Thanks for the tips😅
yeah I was a bit confused about it not being 14x square. I was wondering why you said there was 2 like terms when it looked asif there was 3, I guess you just had the 14x square in your head
i think there is a mistake at 6:18. its meant to be -4b
14x2 + 22x - 12
I don't think I will EVER understand algebra! There just doesn't seem to be anything I can use to visualise the components.
I think you have two woops. It's -4b, and 14xsquare
You made a mistake in 6:22, the final term of your answer is supposed to be -4b not -4y.
I leant more in a 12 minuet video than an hour lesson
hello there, I have jz posted about How to Expand Algebraic Expression involving brackets degree 2 using Binomial Formula.....I hope its helpful
7x . 2x should equal 14x.x ( 14 to the power of 2)
Ammazing
does this guy has a video for factorise?
What is (c-d) squared because I have no idea
Therefore, there would be like terms.
ur wrong at 6.20 its -b4 not - 4 y
few mistakes but I was capable to understand keep up the good work
how about (3c-5d)(-2c), how to do this
