I’m here after what? 5-6 years? I wanted to thank you for being such an amazing human being, I used to watch you and I sure learned a hell lot from you, you were a big impact for me in my teenage years when I was struggling with math so thanks again, keep educating the future generations you are a blessing to this world.

But dude this video is 1 year ago.....how do you come back 4-5 years later
@@lucifermanon yeah this video is 1 year old but he uploaded videos 5-6 years ago too

I have been struggling with factorization since high school. Sometimes math teachers seems to make math looks hard. Now I love factorisation after seeing this. Thank you. Would you please make some more videos on equations that looks harder. Thank you so much. That's why we need people like you on this planet earth. I'am grateful.
I don't know about other countries but here in India we use a method named Splitting the Middle term. This method is a simplified version of it. We Indians use Sreedhar Acharya's Formula(Quadratic Formula) for the equations when the 2 numbers can't be found. The method used in this video is really helpful in solve inequations. That's how I found this video.
Kudos @tecmath
i literally have my maths homework due tomorrow and i had no clue how to do this, thank u i am blessed this is much easier explained 😭🙏
This has changed my life. I've always been stumped by factorising. This has just unlocked my ability to do it. Thankyou.
This was our lecture last quarter and I understood nothing! Thank you so much!
Excellent! Hope you liked it!
Shows how poor a lot of teachers are at their job
@@blue_red_screen I would've jumped out of my chair if you used the wrong "their" here 😂😂
My dude I'm gonna cry this is gonna get me through tomorrow's precalc test
This tip is such a godsend. Thank you so much for sharing it. Love your channel and working my way through your catalog it videos. I wish I could have had a teacher like you 30 years ago when I was in high school.
WHATTTT??? I DID IT. I DID IT.This video is so awesome and help me save so much time during exam. Thank you so much.
Exactly what I was thinking, teachers never explained how they did it so fast. 4:37
That’s awesome! Nothing like that when I was at school doing quadratics in about 1980.
Thank you. Still love mathematics. Now I’ll have to sit down and discover why this works!
Thanks again - AWESOME
Did you find why this works out?
@@sambadivilshit Yes. Yes I did make sense of the reasoning behind the method.
@@SpatialGuy77 And what's the reasoning?
@@SpatialGuy77 ahha idk why I expected you to be the typs guy tp give me a whole essay to explain me the concept of why and how of this thing but cool !
Mate, I'm struggling keeping up at uni with the convoluted explanations that the lecturers are giving. Your explanation is 1000x easier to understand, so thank you!
right before my math test about this, thank you for the time saver
Best of luck!
Fast explanation than my teacher's discussion in my class.Good job sir
Wow! Best lesson on factoring these I've seen thus far. Thank you!
Thank you so so much. going through calc 1 and I've never quite understood factoring. I don't understand why it's not taught like this, it makes perfect sense!
Tysm I have had a hard time trying to understand this and you have manged taught me how to do this in under 5 minutes!!
The last example can also be solve by -6 and 8, thus, -6x8=-48, -6/4=-3/2 , 8/4=2/1.
That wont give the extra 2 infront though
Very informative and simply explained thank you
Just found this channel. UA-cam’s recommended actually came in handy. Pre-Calc is gunna be a breeze now
Ty, i finally know how to do 💀 my math teacher made it so complicated 😭
You are a legit genius, thanks for making this!
The most needed video, thanks man
Glad it helped
An old 32-year-old here who couldn't remember the formula says "Thank you!"
That's crazy , I just learnt it yesterday in maths , this will help a lot mate !
bless you and bless your soul you LITERALLY made this so much more quick and easy, i like this technique of getting the answers and sure will be using it😁
you are just soo helpful,it only took one problem solving and now m good at this .🙏🏻🙏🏻🙏🏻
Thank you so much, I am a year 8 and I got this a homework 😭 now I will beat all my friends thank you so much
I am so glad that you are still making these videos.
a1: (10x-6) (2x+1)
a2: (5x-4) (3x+1)
a3: (x+2) (2x-3)
these where commented before i finished the video. i dont know wether these are right or wrong. good vid!
yay, i got 2/3 right! i always seem to do switch the division and addition signs when it comes to problems like the first :/
thaaankssssss u explained way simpler than my teacher
What of 15 when you add 3 plus 3 they don't give you the sum which is 15?, Enlighten me a bit on that
This needs to go viral
Fantastic explanation, really understood, thank u very much for these easy tricks😊😊😊
you teach better than my teacher, thank you
Literally just learning this in class today, timing is immaculate
My biggest problem is coming up with the numbers that multiply together to give you the multiplication number, but also add together to give you the addition number. Other than that, I'm good.
Thank you so much !!! God bless you! I will watch all your videos after discovering this one! Really grateful!
This is gonna be in my test on Wednesday 30.12.22 and this helped me understand it so much tyyy 🙏🏽🙏🏽
Love the way you explain it👍 may I ask how you can quickly find out the numbers that you need to multiply/plus? I'm afraid I take way too much time trying to find it and then struggling
Concept explained nicely. Great work!!!
Amazing trick 👌 thank you for sharing
Cant believe how I learnt this so quick as an 8th grader
This is a chapt of 10th grade and i have understood this 2 years before i even start to actually learn quadratic equations 😀
I loved it... You make things look pretty easy!!
this is actually an amazing video
Wow, thankyou so much you answered my confusion and questions in the example youve given.
Best method out there
I just asked my friend how to factorise when the x squared coefficient is greater than 1. Cheers
You make students life more simple. Btw thank you so much
2:29 😮 so this is it WHATTT, OK thankssss
how do i find the numbers that add to the adding number and multpiply to the multiply number if theyre big. say muliply number is 400 and adding is 40. it would take too long?
I appreciate this help. This has helped me so much as I have been struggling with factoring. Such a huge help.
Thanks😁
what I learnt from school for 2 month: nothing
what I learnt from this guy for 2 month: everything
saved my life tysm ily bro
i have a question, does it matter if i dont simplify it, like i didn't for the last questiona and got (x+2)(2x-3) which is what he got as well but with a 2 outside the bracket at the start, would it matter if i answer the unsimplified version?
10 hours away from my final exams and I finally can do the part a of my papers with confidence😮ily
One question: on the last example that has the 2 outside the brackets, does it matter which bracket the groups go in? So the answer you gave was: 2(2x-3)(x+2)=0....... The answer I got was the reverse: 2(x+2)(2x-3)=0.... Would my answer still be correct?
the brackets can go in any order, they mean the same thing and you would never be marked down for this in a test :)
X=-2
4X++4---3X--6
3X====3X
X======0
X=-(-6+4)
X==--2
YOU ARE ABSOLUTELY AMAZING!! literally thank you so much for this
Excellent professor!
you can do the last one also with the same method you did the other ones
thanks for the video its great.
You wont get the 2 infront
Can you make a video about factoring polynomials?
Please do a video on how to solve simplification/approximation equations as fast as possible. I've been working on them for a while and i know of only two methods, the Unit digit method and digit sum method. But both are not really viable cause it usually dosn't check out.
Love from Britain! You are really needed here in secondary schools :) Quick question: for the last question you did where you simplified the quadratic, why do we NEED to do that? I understand that we do but exactly why?
same question mate
An amazing tutorial thank you very much
Excellent video! Thank you!
Extreeeeeeeeeeeeemely helpful thx so much
neat trick for factorising quadratic equations, thanks for sharing
Thank you so much I pass my math examination🙏
Oh my god thank youuuu for thus u saves my morning😩😭😭😩😩
great method thanks
Oh my God, this is incredible
How are tou finding the numbers youre using to multiply to get the value and to add to get the value?
Very good. Simple and sleek.
This video helped and still helping me so much
Does this work for every case?
Forever grateful to you, u always save my grades
This is actually a nice trick for the sat
So I expanded (2x+4)(x+3) and it gave me 2x^2+10x+12. I then factorised it back with this technique and got (x+3)(x+2) which is a different answer. I had simplified the fractions for both sides, which were 6/2 and 4/2, but I found that if I had've skipped factorising the 4/2 fraction it would have worked. Can you only simplify one of the fractions? How do you tell which one? Can someone please tell me where I went wrong, or have I broken the formula?
I doubt this will get an answer any time soon as the video is nearly a year old, but worth a try.
2x^2+10x+12 all have a common factor of 2
So you could rewrite is as
x^2+5x+6
Which would give you the same factoring result (x+3)(x+2)
X=-2
8+(-20)+12=
-12+12=0
You are a genius! God sent.
this helped alot thanks man
The way my school taught it us was that you would divide the entire equation with a (ax^2)
Then you would start with the shenanigans of the result of multiplying 2 numbers you get c and adding two numbers you get b
I learn this trick but with a little difference. i put the 4 over the sum product numbers so i can say from top to down, x+3 and 4x+3
This is the way I do it too, I think it’s more straightforward this way.
This is so cool. TYSMM
Wow 🔥🔥bs isski hi jaroorat thi mko. Jeevan ka kasht dur ho gya 😀😂😂
hello! do you know any faster techniques to get the numbers that add up to x and +? Example at 7:38, my head really cant wrap around those type of stuff!
prime factorize the coefficient of x
thank you so much!
Thank you!
Yeah this was neat. Definitely another perspective
Insanely easy. Thank you.
Thank you v much indeed. This is great channel.
Really good explanation.! Thankyou...
I see your a man Of Math as well!!
Thankyou sir, this is wonderful.
Useful as usual 🔥
I cannot get this to work for 12x^2 + 8x which should be (X=4)(3x-2). Is there a different rule or an exception?
Very nice presentation sir.
Thank you so, so much.
Nothing short of amazing!!+. Wow.
very thanks
Thanks Thor
thanks
