First time I joined your Live class and it's awesome I really loved the way u r explaining sir Thank so much sir for all your great effort for us 😊😊😍

[@dheerendrashukla6733]

Really Bhaiya, no one can teach better than you (at heart 💖)

[@preetigupta5959]

U are the great sir ❤️ ek bio student ko bhi ab maths me interest aane lgaa hai 😅😂

[@KrishnaPuriGoswami-2106]

Sir, I attended your class today for the first time U have explained each and everything very patiently Thank you so much Sir Liked the class 👌 a lot 👌

[@shivamraj-up5qg]

Thanks a lot sir. Thanks for curating all the concepts of quadratic equations in one video using previous year. Very very useful for students who have completed their quad and coming here for practice. The best part of this video is sir have explained each and every concepts.

[@TessyQuirkyTales]

Thank You So Much Sir, Aapki wajah se saare concepts clear ho rahe hain....

[@kunal955]

i have no words for your efforts sir !! ❤❤❤❤❤❤💕💕💕💕

[@Sonukumar-ud8ro]

Thankyou sir for this amazing session

[@rahuul_finance]

1:06:58 correct would be → ( alpha - beta ) = √D / a hota hain.

[@diptimallick4145]

sir you are the best !!!! the way you explained the questions is very easy to understand thankyouu so much

[@gajendrakumar-zy2fe]

Sir please inequalities ke pyq pe bhi ek one shot session bana dijiye 🙏🙏🙏🙏❤

[@MusiwoodRj]

Sir your great ❤️

[@ArbajKhan-wg4oy]

Sir please upload function and graphs pyqs as well

[@ojasgatkal]

Great session sir 🔥

[@mbagirl03]

Thnk u soo much sir

[@nakothenakothe]

1:27:46 pe sir apne sum of root ki value b/a li h -b/a lena tha ie- -(a+3)^2 pur sumof root b/a se answer kaise aa rhaa h?

[@rajveerthakor3585]

Bro it happened coincidently... Like if we take -b/a the the expression will become (-a-3)^2 right.Then when you will expand it, it will become (-a)^2 + (-3)^2 + 2(-a)(-3) which is same as (a+3)^2. i hope my explaination is good enough

[@rajveerthakor3585]

Otherwise you are absolutely correct. sir took the wrong value and still got the answer right but its okay. Even sir is a human being

[@viratmaurya5080]

in first question why not we take x+1=x(square) other side like, -x(square)+x+1=0😕😕 please let me know

[@arati8600]

Thank you sir ❤️

[@brainstormmedia432]

Sir in the second last question it should be n^2 > m. So why have we interpreted n^2>= m

[@jaspreetsinghgill7338]

sir hats offff

[@foreverraushan1932]

best sir jiii

[@karan71411]

1:05:01 pe ans 5/4 hoga bcz at the time of (a-b-c)square u made a mistake of writing +4v instead of -4v

[@rohansingh7037]

Great teacher ❤

[@meenusharma4511]

great session sir 💓💓

[@kavithviswanath1052]

Sir, at 1:56:12, if we substitute the options in the equations, we will get positive values for all right? Why don't we do it that way? Further, even in the new eq you had made afterwards, if we substitute 6, we will get 5 as the answer which is higher than what we got for 12

[@ramantiwari1205]

Kavith here we have to find the maximum value of n, aap overall function ki maximum value check kar rahe ho... hum function ko simplify karne ke baad n ki jitni maximum value lenge overall function ki value utni minimum ho jayegi, kyuki simplify karne ke baad n denominator me hai, that's why maine equal to 1 put karke solve kiya kyuki 1 is the lowest positive integer... and thereby we will get maximum value of n

[@AyushBhagawatiYT]

Thanks, sir! Had the same doubt

[@sahilnanda9812]

Thankyou sir

[@factFuse845]

Sir you are amazing in your skill your teacher and also in making us laugh 😂😹❤️🙏🥺

[@dhruvkeswani8948]

sir, the question in which we had quadratic equation both in power and in base, shouldn't answer be 12 with integral values 1 to 12??

[@dhruvkeswani8948]

the equation in power can alone have 12 roots, each time taken a positive value in RHS while having base as -1

[@jyotshnakashyap2013]

Sare chapter k karoge sir pyq?

[@a31abhinavkumar79]

is pyq enough to understand and prepare for exam??

[@crickettoday9891]

Nah! You need to solve lod 1 nd 2 of Arun Sharma

[@soumadityasinha3750]

Doubt: (1:39:40) The question says "must necessarily be" but there are points on the Y-axis nearby origin which do not give solution, so how can we consider set of "all" integers? I got the answer: empty set (must necessarily)

[@ramantiwari1205]

1.X axis is a part of domain, so we will check it through y axis... 2. Since here sign of a is not define.. So it could be upward or downward parabola... 3. In case the result is upward parabola then s will be empty and in case of downward S will contain integers that's why B option is correct

[@soumadityasinha3750]

@@ramantiwari1205 i got this point of yours, sir. But my doubt is that the options mentioned "all" integers If it was mentioned set of integers, then definitely option B would have been the answer due to negative 'a' but in the option it mentions "all" integers

[@mbagirl03]

24:02 sir can we take x=6, 1

[@laviina.13]

nhi we can’t a tip is 6 ke pehle + hai to ese numbers lo jinka + hone pe middle value (5) aaye. 3+2 it is. This isn't a rule just a quick trick. 6 and -1 will not work.

[@aniketraghuwanshi3618]

Sir if we will go by options then 8 and 12 both will fulfill the condition

[@ramantiwari1205]

Can you please share the time line of your doubt

[@aniketraghuwanshi3618]

Sir in the last question, if we directly put the largest values in the option then @@ramantiwari1205

[@manitiwari9233]

the question asks for the largest which is 12.

[@harshitkumar4344]

[@amansaraf6016]

1:42:00 me k^2=40 hoha nh

[@ramantiwari1205]

By mistake likh diya tha maine, aage thodi der baad correct kar diya tha
