@@Shubhu519 it's actually a good question 😅 In my opinion we never divide by a²-5a+3 itself. We first divide the given expression in x with the quadratic x²-5x+3 and THEN put x=a and x=b. So it must be valid
In case of the first question the value of 'a' has to be negative. So, the answer choice (a) is correct and it also satisfied the given condition a + b = 198. It does not require so much calculation. This way it can be solved in a few seconds.
27:10 isme tranformation se simplify kar sakte hai just put x=alpha in original eqn multiply by alpha to get alpha cube then simplify new root as roots are symmetric use transformation. que done and dusted
arvind sir and nv sir are literally our saviours for maths....I cant thank enough the unacademy team for providing us these type of amazing content on yt....
Sir, in 1:46:34 even if p takes its value as 2, k will be -3, which is allowed and magnitude of k + p will still be 1 , hence it satisfies for all the cases
In case of third question the roots of the given expression should be equal. Answer choices a, b and c do not have equal roots. So I think the answer choice 'd' is correct.
Sir ek request hai level up session ke baad aap ek sheet provide kariye jisme 5-10 unsolved and really good questions ho... Btw loved the session sir ❤
Bhai ek baat or hh ,abhi tak Trigonometric equations and sot. Nhi hua hh. Bhai plz jaldi se jaldi ye chapters channels par cover kr dijiye. Thank bhai ❤❤❤
In second question minimum value of x is 2 so put x=2 value of a will be also minimum and after putting a comes as 7/3 that means value of a milust be greater than 7/3 this is only in first option
In case of the second question, the curve is concave upward. So its 'y' coordinate has to be positive. Therefore when x = 0, a - 1 is positive. The answer choice (a) is correct. It does not require lengthy explanation.
14:56 sir cam we directly put the value of x =2 since it can never be greater than 2 so the minimum expression of value comes out to be 7/3 so 1st is directly the forst answer
sir i have one doubt in last question wo aise bhi to ho sakta tha ki gamma>alpha>beta beacuse wo ak andar or ak bahar dusre root ki side me bhi ho sakte tha
Sir in last question (2:34:35) , alpha aur beta pe value opposite aa rah heh this mean a root lies between alpha and beta but since it is a quadratic equation it contains two roots so how are we sure that gama is in between alpha and beta, another root can also satisfy na?
Sir pls reply Sir mene padha toh he per jyada practice nhi ki question ki Regular base pe question nhi banaye sir I am not confident about any chapter other then set
Bhai please tell me what should I do. I am in 12th currently. according to me October end Tak Mera syllabus khatam ho jayega to please ye batado ki kya karna he mujhe uske baad. Abhi me kisi platform pe nhi hu to kya koi test series Leni chahiye ya kuch aur aur ha to konsi please tell
After 12th syllabus completing, u have to focus on 11th revision and regular testing to keep 12th intact. Test series ka major fayda, full syllabus tests mein hoga. Just make sure u complete ur 12th syllabus so strongly that from nov u may focus majorly on 11th revision....❤❤
Mere khayal se correct hona chahiye kyuki iska graph concave upwards banega to a>1 hoga. And x ki minimum value pe a ki jo range aayi hai wo hi longest hogi kyuki uske baad x ki value badate jayenge to a ki range kam hoti jayegi matlab a ki range me 7/3 se Chhota koi number nahi aayega
Class 11th student here... In the first question only option A values for a amd b add upto to 198. B is -200 when we add its values C is -198 amd D is 200.... am i doing something wrong?
Vote for sequence and series ❤❤❤
Yes we want sequence and series level up
Aa gya bro
6:57 since sum of root is +ve , -a>0 so a
Good thought Prachi.... 👍👍
Thankyou sir @@JEEnexus
Nice approach thanks 😊
ummm arent b,c,d eliminated just from a+b=198
🤔🗣️🔥@@Rahul-dc7vo
Please do these types of series again and again. Very useful. Best teacher
Bhai esa hi Sara chapters ke advance level questions jee mains 2025 session 1 se phela kara dijiye ga.
Apki bhut kripya hogi ❤😇😇
thank you Bhai for problem solving session ❤❤❤❤❤❤❤
27:06
X²-5x+3=0
Therefore a²-5a+3=0
Now 2a³-10a²+7a-1
==> 2a³-10a²+6a+a-1
Taking 2a common
2a(a²-5a+3) +a-1 ==>a-1
We can do this way too..
Yes shera. Its same as division algorithm only... But done in a smart way...❤❤
in vid he divided by a^2-5a+3 but it is 0. how can we divide something non zero by 0
@@kaliaiit thanks sir

Mera bhai , Arvind sir ..
sir your thinking process is amazingggggg
Amazing session with very relevant and thoughtful questions
Very helpful , thankyou bhai❤❤

bhai iss question mei humne a^2 - 5a +3 se divide kese kara, like woh toh 0 ke barabar hai aur we cannot divide by 0
The answer for the first question can be found in seconds without solving the question. I am a senior JEE Maths faculty.
mhm due to the options no?
Yes you are right bro
Anyone who studied integral roots and even have CS can do it easily without pen
Solution sir pls @somuapti
@@DarshitSharma-ll2ij When two roos are positive, the value of 'a' is negative. So the answer choice (a) is correct and it also satisfied a+b = 198
Yeah, I did it by just checking sum of a and b from options. 😂
arvind sir and nv sir are literally our saviours for maths....I cant thank enough the unacademy team for providing us these type of amazing content on yt....
I watched your vedantu elite class 11 that helps very much. MERA BHAI...
20:00 good question
bhaiya this is brilliant, please make level up sessions for all jee advanced chapters ❤
1:03:42 We can use induction to prove T(n)+T(n-1)=T(n+1) (and also if alpha>beta then this is just the fibannoci sequence)
Best Maths Sir in the whole world , really thank u soooo much sir
Sir, in 1:46:34 even if p takes its value as 2, k will be -3, which is allowed and magnitude of k + p will still be 1 , hence it satisfies for all the cases
THANK YOU SIR PLEASE CONTINUE THIS SERIES ITS SOOO GOOD FOR REVISION
Thanks Bhai itna acchi series lana ka liye❤❤❤❤
Mera bhai ❤❤
Bhai saare chapters k ayenge ????
In case of third question the roots of the given expression should be equal. Answer choices a, b and c do not have equal roots. So I think the answer choice 'd' is correct.
Continue the series😢😢😢😊
Sir do this for every chapters before jee advance2026
sir straight lines please
Sir this series is literally helpful
Sir ek request hai level up session ke baad aap ek sheet provide kariye jisme 5-10 unsolved and really good questions ho... Btw loved the session sir ❤
GOAT of Maths .. Arvind sir
Thanks a lot bhai it gave me new ways to look at these problems ❤
Please SnS ke liye bhi aisa session laiye ga plz 🙏
Bhai please tell me agar ye series ko follow karte karte 11th ka revision kare to best hai kya??
Thank you bhai❤❤
Sir more sections like that,please❤❤❤❤❤.
Bhai ek baat or hh ,abhi tak Trigonometric equations and sot. Nhi hua hh.
Bhai plz jaldi se jaldi ye chapters channels par cover kr dijiye.
Thank bhai ❤❤❤
Your explanations are so good sir, thank you for the session ❤️
In que 3 we can satisfy Alpha in quadratic and after multiple both side by alpha to get cubic and it would cancel to a linear root
In second question minimum value of x is 2 so put x=2 value of a will be also minimum and after putting a comes as 7/3 that means value of a milust be greater than 7/3 this is only in first option
23:30 sir can we just put x =2 in the given inequality and then conclude a>= 7/3 ?
Vote for complex numbers ❤❤
Pls i need this
In case of the second question, the curve is concave upward. So its 'y' coordinate has to be positive. Therefore when x = 0, a - 1 is positive. The answer choice (a) is correct. It does not require lengthy explanation.
But from this explanation, both a and b are correct. How to eliminate one?
Okay no problem I figured it out. Putting minimum value of x i.e. 2, we get a≥7/3.
Amazing sessions
Thanks you sir
Pls make for more chapter.
Sir for seq n series also plz
Sir this session was very helpful Please take other chapters too
Bhai ek request hai please ye sessions physics ke liye bhi le aaye it will be very useful❤
Sir plzz make this for chapter Plzz it's much helpful
Bhai ese he ek complex number ka bhi kar dona
Sir please complex numbers
14:56 sir cam we directly put the value of x =2 since it can never be greater than 2 so the minimum expression of value comes out to be 7/3 so 1st is directly the forst answer
Same thought
Sir please provide us pdf of questions of this level up session. This will help when we try this question.
sir thank you for this sessions
Sir pls make this video for circles and straight lines 🙏
Bhai please do trigonometry ratio and identity and trigno inequation combined one shot
Sir Last ke kuch sawal kya he amazing the mtlb maza aa gaya
While solving the third question, Sir has equated x^2 - 5x +1 = 0. It is wrong. Actually x^2 - 5x + 3 = 0.
4:08 lecture starts
Sir please create a playlist for this can't find a seperate playlist for this...
6:57
-202+400=198
200-400≠198
202-400≠198
-200+400≠198
So right answer is only option A
No Need Calculations
good 👏👏
sir i have one doubt in last question wo aise bhi to ho sakta tha ki gamma>alpha>beta beacuse wo ak andar or ak bahar dusre root ki side me bhi ho sakte tha
Sir sequence and series ka bhi level up lao na jaldi
Sir me wahi yogesh jisne aapse pucha tha next chapter on TH-cam sir next chapter trigo kariye please ❤❤❤
Sir please start straight lines next
Pleaseeeee
26:45 sir agar x2-5x+3 ki value 0 hai,to fir humne ek expression ko usse divide kaise kardiya?
Kya ye class11th wale bhi dekh skte h kya
question at 1:48:00 is wrong find beta and then cos^2Q and sin^2Q ans is irelavant
sir pls physics ke bhi one shot laiye
1:43:20 p ki value 2 bhi to ho sakti thi??
Playlist for this ?
Sir pls make this video for sns chapter 🙏🙏🙏🙏
Sir please update the pdf of the session
Sir in last question (2:34:35) , alpha aur beta pe value opposite aa rah heh this mean a root lies between alpha and beta but since it is a quadratic equation it contains two roots so how are we sure that gama is in between alpha and beta, another root can also satisfy na?
Same question bro . Gamma can be the other root . It can be in front of both alpha and beta . Making it not lying in between the alpha and beta .
where can we get the pdf

Sir pls reply
Sir mene padha toh he per jyada practice nhi ki question ki

Trigo ke liye
16:28 sir vo eqn mein x=2 substitute kare toh nahi hota hai kya (answer to aayegi ) kya har bar correct hota hai
Mere khayal se correct hona chahiye kyuki iska graph concave upwards banega to a>1 hoga. And x ki minimum value pe a ki jo range aayi hai wo hi longest hogi kyuki uske baad x ki value badate jayenge to a ki range kam hoti jayegi matlab a ki range me 7/3 se Chhota koi number nahi aayega
