Lmao I'm in 8th grade this is what they teach you in 8th grade when you're in pakistan

@@feasty_uwu301 sheeeeesh

@Feasty_uwu in uk they teach u this aswell in 8th grade

@@amilea9092 yes

I’m in Singapore and they teach it at the age of 13 in my school ;-;

Me too 😿😿😿

me too. I can't find any good videos and I'm doing summer work so I can't even ask anybody :(

Me too 😭😭

@@lowririchards2913 jus watch it 3-4 times u must understand it by then inshallah. Dw ima pray that u do

bestie i hope you got it cos i didnt

You're welcome.

I'm 3 out of 4 in only math left🤞

GED? Thats no good

Whats GED

@@alyssa63902 Good Enough Degree. Its when you cant pass high school because you became a teen mom or you're stupid so you get a mini high school diploma

Bracket is more easier than that

Skip the bracket misery 😂 all we want is X

Harrison Juhasz ....yeah it was also taught to me....

they do

Harrison Juhasz I actually learned that at highschool

they do..i thought this was going to be a different method ,,nvm lol

it's taught but it's not efficient. Just use formulas, you will save time.

with fractions which i didnt know how to do

How is this the quadratic formula but written differently? Where is relation to b squared and square root b^2-4ac?

@@naheemahakinwale8403 Exactly! I'd have liked him to explain why it works. Now I will have to figure it out for myself. I love these short-cuts. When I was young, I had a book full of them. Unfortunately, I don't know what happened to that book or what it was called.

no. in the quadratic you have to do a square root. Here you don't. You do only factoring and addition/subtraction. This is why it is easier... at least when the results aren't great zonking multi-digit decimals. I learned squares up to 14, but not to 17. So if you don't know that 17 squared is 289 (the discriminant) then you really would have to solve for the square root, which is a nuisance unless you know the shortcut for that...

You get the same answer. Not the quadratic formula but an alternative that always works and is way simpler lol

Yeah in class i dont listen fot a minute and the class just finished a semester but this is easy

I didnt, im crying because i will never get this

You are though this before high school

shut up you liar

I learned this when I was 11 so if your 57 years doing math, your in the wrong career.

@@TheRavensdomain he maybe tell the truth why a liar ?

@@interestingman6934 oh no im sorry i dont know why i said that

@@jamieparke8235 not necessarily if he's working with math for 57 years he definitely knows how to do it but to most mathematical problems there are several approaches he simply stated he had not seen this one

It's also an example question from a CGP book

same bro wish me luck on my final exam tomorrow. I currently hold a 96% in math

@@dee2vee122 The greatest luck is wished

they dont teach it because then the teachers would spend more time in class waffling about defferent methods and they get paid more

Thanks. I used to find this pretty painful too!

if you have dyscalia and you want to learn maths on this channel through memorizing than you will want to learn maths logically without memorizing.

That's real method. He did this is in short cut method.

@@sheetalswaroopburada Yeah and he showed them in shorter ways.

@@divyoroy9056, Tecmath's 'way' is actually the same, we guess, as yours, but he (she) jumps it by a couple of fast tricks, without showing that the way is a right one, without showing that the results are really the roots of the thing. Your way shows up more mathematical, walking step by step and proving the rightness of each one. And so did our teacher, and did we, on school (continental Europe) years ago. Know what you are doing, prove your readers and yourself that it's right in any step, that's the beauty of algebra. We still prefer your way, that is, your way of taking logical steps. A little more ink or chalk, and then so totally clear!

@@keescanalfp5143 thank you for appreciating my way of doing these quadratic equations.

Why blaspheme koseiH? God is the Master mathematician, and the Lord Jesus His only begotten Son.

Thanks

Sloan Bell exactly... I’m confused now.

That's what you're meant to do. Factorising is a just method among others e.g Quadratic Formula or Completing the square. If you continue this question to graphing, those two values for x would become the x-intercepts for the parabola.

Sloan Bell Also you can just use null factor theorem to factorise the final answer

just go with another step and u have the factored expression

Thats what school is...

Mia Hayes no school math has reasoning to why ur doing something like u can figure out a problem that u don’t know how to solve but this is all memorization

@@tomaliafern4219 It's that it is only memorizing, but the purpose of "tricks" like this one is for doing things quicker. If you want to know why it's like that, you can try and prove it, an exercise for your brain. But once you're sure it works (either from proving it or because of trusting this channel, which i personally recommend), it just makes your tasks suddenly much quicker to do.

I'm a mathematician and high school math teacher and I endorse this video. To the critics, how many of you do difference of squares all the way out? Or do square roots by hand instead of using a calculator? Do you use the standard paper and pencil way of dividing? THat's a trick too, as is multiplication of two digits by two digits that we were all taught. Sometimes the understanding comes much later or is irrelevant.

Its british

@@whatcomment5331 It's clearly ozzie

init haha

r u kidding me his accent was disgusting i was gonna puke

FACE PALM atleast he tried

To factor it, all you have to do is take each solution and rearrange it to make it equal to 0 e.g. x=2/3 => 3x=2 => 3x-2=0 x=-1/2 => 2x=-1 => 2x+1=0 So 6x^2 - x - 2 = (3x-2)(2x+1)

Exactly

Its exactly what I needed

@@mumtazraja4609 Thanks, this helped me :)

NukeML Yes, some of them you have to use some fractions to find the blue numbers.

Yeh if they aren’t factorable

this is when you need the quadratic formula.

x = -B+- square root of (Bsquared - (4AC)) ALL OVER 2A

(Quadratic formula)

Karan, don't be so rude and ignorant. Have some respect for someone who is trying (and succeeding) to help!

Karan - why tf u so rude

I dont get. Its a liitle confusing at the end i only get the first part 😞

if you think really hard about it, maybe people who have just begun learning this stuff, or don't have a good teacher, or have already forgotten some of it, might not know this
