i didnt find this much explanation even in IMS coaching center...thank u so much sir
This video is Quad. eqn video 4....there is no cubic eqn 3 video...so finish the quad. eqn till video 3 and then come back to this video...
R yu sure?
this is the quad eqn. 3rd video and the 3rd video mentioned in the playlist is actually the 4th one.
@@swatibisht4572 thanks
can you send the link of cubic eqn 3rd video
@@saravanansk3342 There's no 3rd video.
Thank you sir...a few days ago I was scoring -ve in mocks but today it was 70%ile (not enough but for me it was an achievement) credit goes to you. ❤
Hey brother from where you are taking mocks ?
@hilopfreefire1414bw
Am i the only one who felt overwhelmed when sir said "it's my guarantee"??
at 6:00 can we take K = 0 ?
if we do so, then it would not be a Quad. Eq.
at 6:00 can we take K = 0 ?
if we do so, then it would not be a Quad. Eq.
thank you, sir. You are better than paid coaching present on online platform.
these kind of approaches are must for cat ❤️
K belongs to [-1/11,1] -{0} and therefore it has only one integral value.
i am also getting , can someone verify
@@siddharthchoudhury4158 if K=0 then the equation will no longer a quadratic equation as it becomes linear equation, that's why K can't be equal to zero.
sir thank you so much for all of your efforts and hardwork, everything is explained properly .
.
ye lecture cubic equation ke naam se kyun hai ? Or ye quadratic ka kon se number ka lecture hai please btao , confused hun bht , or ye bhi ki cubic equation ke kitte lectures hai
First question: k should be less than 1 and should be LESS than -1/11. This means k should be greater than 1/11(which sign changes, inequality changes). Which implies k is less than 1, and k Is greater than 1/11. Which means there is only one integral solution, ie 1.
range is provided k is equal or greater than -1/11 and less than equal to 1 soin qns integral soln asked so k can be equal to 1 and 0 only 2 solutions.
At k=0 it won't be a quadratic equation .
@@alokmittar1034 k cant be 0 otherwise it will not be quadratic equation.
Extremely Humble and an excellent teacher, absolute legend. Thank You for everything dear sir.
This Glowing Educator needs to answer me this.
Where be the quizzes?
Was it not supposed to be 3rd part of cubic equation & not quadratic equation??
Ya searching for the same!!
8:50 yes sir very new thing 😂😂
Thankyou so much sir.This video addressed so many questions that I was struggling with
Hiii can u please share me these notes of algebra section in handwriting notes scanned format please
sir I think that number of integral values of k will be 1 because we will not consider k=0 as the quadratic equation will then become a linear equation
Good observation
@@arjitkumarprince5537 Yeah, in a way that's right, but should we consider this?
Arunaditya Raj Jain absolutely... this is the first important condition for the equation to be quadratic . a=/= 0
Yeaa you are correct✅
Sir, inequality sign also changes with the sign change of numbers. k will come to be -1, 1/11
it doesnt change the solution rather changes the limits of the solution
Sir great video. Please tell me where to find your quizzes?
Thankyou 💜 so much sir 🙏🏻
In Q1. of Maxima and Minima, i am getting different values. For X=5/4, it's 149/8 and -D/4a, it's 447/112. Please someone helpme out here.
isnt it cubic equation continuation?
Why did he take -alpha -1 in product pq I mean sign should have changed right? Like -(-(alpha-1)) ???
thankyou so much sir .
Cubic Eqn 3 is actually Quad Eqn 4. And in this video, you said that next things you would discuss in next videos. BUT WHERE IS NEXT VIDEO???
I am preping for this yr CAT and fully relying on you.
Sir kindly upload coordinate geometry lectures as well please.
how 5 in the last minimizing dint get that part
Thank you Sir 🙏.The video was amazing.
18:34 can someone just explain if it's -b/a then why did he took alpha -2 and ig ignored the minus sign whereas in c/athe minus sign was includes
Quadratic equation is of the form ax^2+bx+c=0 here b=-(alpha-2) c=-(alpha+1)
b = -(alpha - 2)
So, - b/a = -(-(alpha-2))/1 = alpha - 2
Hope, this helps
Thanks !
Why can't we use the formula -d÷4a for finding the minimum value in the last qst??
sir, or anyone else ...can someone please tell me where are the QUIZZES ???(which sir keeps talking about)
Sir in the question f(x) = 6x^2-15x+28=0 you have calculated minima but how we can calculate this because the D of f(x) is negative (D
at 6:00 can we take K = 0 ?
if we do so, then it would not be a Quad. Eq.
Thank You!!!
Thanku sir
how many lecture of cat is not avaialable in this series plzz anyone tell me
same question
Sir in the first question, k cannot take 0 as it will not be a quadratic equation so there is only one integral solution
Sir can u please share the quizzes about which u are talking.
4:03 , the sign of inequality should change ?
19:31 - pq will be a + 1 ?
Hello Ravi Sir,
This video is of quadratic equation probably the 4th part. Therefore, I request you to change the name for other students' clarity and ease.
thank u sir
sir where are the quizzes can you please tell me i want them for practice.
Did you found quizzes?
Sir, Which video has Descarte sign change rule?
Same doubt where it is ?
Sir , k should be less than or equal to 0
Therefore answer should be 1 ..not 2
Is this true ??
Koi btayega ki ye quadratic equations ka kon sa lecture hai , or ye cubic equation me kitte lectures hai sir ke
This is quad lec 4 and cubic has just 1 lectures
Where are the quizes?
why isn't -1/11 included in the solution??
yea man same doubt isn't -ve numbers included in integral sols too
Please change video name cubic to quad equation 4
At k=0,it wont be a quadratic equation
Where has this graph been taught?
And wasn't it b^2-2ac?
Graph has been taught in first video on quadratic equations, i.e., next video.
No, it is b^2 - 4ac, always been, right from the beginning of mankind.
@@rahulsinghchauhan6182 bhai bhalai kerne mn kya jata hai? Kya pata vo dubara exam ki taiyaari ker rahi ho ?
@@rupalichaudhary7128 😂😂
Came here for same doubt
@@arunadityarajjain1129 haha good one
where can I find quizzes ??
Can someone tell where are the quizzes?
sir is playlist ke alwa bhi kch concepts rehgye hai?
what is differentiation?
commerce student ??'
3:29 how did u split the middle term? can anyone explain?
always go like sum product
We are factorising it check simple equation videos
🙏🙏🙏
Sir in last question ,why are you take -2Pq
same doubt
sir, where will I get the quizes plzz reply.....
who created this playlist this is so confusing
tiktokers k liye nai hai bro...
@@krishnapatel3755 🤣🤣🤣🤣
Earlier u have taught for b^2 - 2ac n now in this video u have written b^2 - 4ac.. Which one is correct n where to use plss tell
Discriminant of Quadratic eqn is b^2 - 4ac
I am extremely disappointed sir, You have mentioned that 100% course is covered but it is not. You have deliberately deleted topics from all the chapters. Please at least mention that the course doesn't fully cover all the topics. So many students are relying on you
I have not deleted a single video, just relax and enjoy learning. I will keep on adding.
@@Rodha Sir if any important topic or concept is missing in algebra playlist, please let us know so that we may complete it from any other source. I am asking you for this because we don't know the syllabus better than you.
P.S - Thank you for everything you are doing for us. If there's a heaven, then God has reserved a special place there for you and selfless educators like you.
i dont think he has deleted anything bruh
calm down man, there used to be guy like this called sumeet Malik in DSA learning community and when he came onboard with scaler , he deleted all his content
Not the same with him , he must have fought for this because companies don't want their content afloat
He is a angel ❤️
Bkl Sumeet Malik 🤮🤮
