Mr. Organic Chemistry Tutor, thank you for another fantastic video/lecture on How to Factor Difficult Quadratic Equations in Algebra Two/College Algebra. The oldest method that's known to the human race is the Quadratic Formula, however there is a trial-and-error method that can be used to factor difficult equations in Algebra One/Two.
@@ffuurtxit8-wi5fhyou won’t see them likely, but if you do you can try grouping / cross multiplication methods otherwise use the quadratic formula or you’re screwed
@@nPCmp How about with this method? ruclips.net/video/LZ1l5hWF7IM/видео.html (This is applying the method for this specific problem, ruclips.net/video/tzlxjPbKDfA/видео.html ).
Hello Mr. Organic Chemistry tutor this method is too lenghty for many competitive exams and will consume a lot of time. Is there another way to solve these problems??
@@andreabovolenta1226 took me a minute too, he did it because he needed to get 12 from the equation above at 4:27 So he divided 12 by 4 (the number he had) to try and figure out how to make his equation model the equation he started with
if you factor the equation like 3(4x^2 +81x- 63) it would be easy to factor , it will be 3(4x^2 + 84x -3x -63) => 3( 4x(x+21) - 3(x+21) => 3 ( 4x-3) (x+21) . smth like this
@Ryusuke Graal This method is probably better. ruclips.net/video/LZ1l5hWF7IM/видео.html (This is applying the method for this specific problem, ruclips.net/video/tzlxjPbKDfA/видео.html . . . see the comment by the video uploader as well).
@@-.SkyArt.- after you factor out a 3 you have to do trial and error after that. Without practice it made be hard to do but after 1 year or even just a couple hours you will get the hang of it.
I am solid at math. Rolling through some of the maddest calculus classes with ease. Until I run into 5890x^2+4590x+800... Have to factor this for a partial fractions integral.
Jesus loves y'all. Not tryna force religion, but spreading the love of Christ. Your never to far from God, He loves you and everyone else so much He sent His Son to die for us and rose up. God bless.
That doesnt matter, the answer would just end up with decimals. But usually in school they never give you equations that include decimals that are also hard, So if you're in school you shouldnt worry about that just yet. Once you're studying something in a university, then it could become difficult.
That doesnt matter, Once you divide it by 3 you simplify it, If you dont want it to be simple or you just dont care, You can solve it in the exact same way he did in this video.

this is useful if calculators are allowed, I have a final that doesn't allow calculators and we need to finish in a small amount of time
just divide the equation with 3 so you will get as new equation: 4x^2 + 81x - 63 = 0. I hope this will easily get your roots of this equation.
@@jayesh44781 what if they are not divisable
Then it will not come to your exam
Don't worry ☜☆☞
@@ffuurtxit8-wi5fh i hope u agree with me

Bro has been carrying me since middle school, now I’m a junior in college and I swear he makes this shit more comprehensive than professors
im not in college/university yet but i 100% agree this guy is so much more efficient and hes so much better at explaining than my teachers
THANK YOU, THANK YOU, THANK YOU!!! YOU ARE DEVINE!!!
First step should be 3(4x^2 + 81x - 63) no?
Jacob Koel if you want to factor it yeah
Quadratic formula is easier

certain times there are no common factors
we call it shree dharacharya method. I can be derived by using completing the square method
Your original answers + 3/4 and -21 @ 3 min 44 sec were the correct answers. If u plug either number back into the equation it will equal zero.
he was trying to factorise the equation not solve it
such a useful and easy method
Thankyou so much
It’s -b plus or minus the square root of b squared - 4(a)(c) all over 2a.
How do u get those high numbers to be squared
calculator
They usually give you a book to refer to the square roots from
wow, you need to teach my class! Best!!!
4:25 how'd u get the 3? I mean if i were given a harder equation, how will i determine what to multiply to that part of the equation?
The Gcf of 12 is 3
Hello Mr. Organic Chemistry tutor this method is too lenghty for many competitive exams and will consume a lot of time. Is there another way to solve these problems??
Thanks so much sir God bless you and shine his face upon you
4:27 how can you add a 3 to it? Where did you get 3? You've been very helpful btw its just I don't get why you added a 3.
Nvm i get it, I forgot about the GCF of 12. Nvm thanks alot. You've helped me out and I thank you for that!

You can factor out a three and is not hard to factor after that
PLEASE HELP HOW DO YOU FACTOR IT AFTER THAT

THANK YOU VERY MUCH MR ORGANIC CHEMISTRY TUTOR
Saved my life ong fr fr
how did you get the square root?
there's a square root algorithm you can learn from that

Thx for help
Thank you very much sir
Can you solve such a equation in the test when you dont have calculator:/. We need a way to solve big equations without calculator man
I think it only works when b is higher than c
no , it works in all cases ,only in this case the value of x might me an imaginary number

Respect your religion 'n' all, but what does Jesus got to do with solving quadratic equations?
thank u so much
What do you do it its not a perfect square ?
What if after doing the quadratic equation the square isn't perfect??

This is quadratic formula..it takes more time to do...
mr.if the not quadratic number what is that
amazing
hyy bahoot aasaan method hii !!!
where it came from the 4?
What if the number can’t be squared
now how tf can i take rooots of those numbers
can't really understand how you addded the "3" at @4:27
the gcf of 12 is 3
So this is algebra on steroids
First u should have divided the whole eqn by 3.. isn't it ?
Yeah just put 3 on the outside with all numbers divided by 3 and in the brackets. That's what I though
That doesnt matter, Once you divide it by 3 you simplify it, If you dont want it to be simple or you just dont care, You can solve it in the exact same way he did in this video.
you always try common factorization first
Are you sure it wasn't easier the other way?
God loves y'all❤
Really it's too big method
all that, why not just divide 2,268 by 9
can you explain?
why does bro write out his X's like that
💀💀💀
like everyone else?
@@charg1nmalaz0r51 and how is one suppose to tell the difference between X and the mathematical x

Wtf is dis 🤣😂
i love you
WTF 😂
Still time consuming.
This is extremely extremely extremely extremely extremely extremely extremely extremely extremely extremely extremely extremely extremely extremely extremely extremely easy 😑😑😑😑😑😑😑😑😑😑😑😑😑😑😑😑 sry
Why not factor our 3 from the eqn to make it a bit simpler
