Time Stamp:- 3:07:39 to 3:09:20 & 3:13:09 to 3:14:03 has been blurred as I interpreted the question wrongly. So just to avoid wrong information being passed to you I blurred this part.

revision pointers:
1)watch recap of newton identity 3 types of qs, from 55:10 to 56:45
2)mod of difference of roots= (underoot D)/mod a
3.57:43 to 58:25
4)in a quadratic equation, if the coefficients are real, then the imaginary roots always occur in pairs, generic statemenet hai ye
5)2:06:35, in such equations, always observe that one root is 1
6) common roots how to remember formula, watch from 1:52:50 to 1:54:20
7) -b/2a, -D/4a, these are the x and y coordinates of the vertex of the quadratic equation graph parabola
8) 1:40:28 to 1:44:38(transformation of quadratic) AND REMEMBER THAT THIS SHORTCUT IS APPLICABLE FOR EQUATIONS OF ANY DEGREE!!

Sir I feel like you are one the most underrated teachers on YouTube....your hardwork and knowledge comes out from the way you teach..🙇

[Its_unknown-crazy]

Sir I am from allen and I studied quadratic a month before and I forgotten a lot of things and then I accidentally discovered your shots in which you are saying to complete straight line circles and quadratic equation within December so I decided to start with quadratic equation and the session was very amazing I completed it and when I am reading my Allen notes it seems like everything I could grasp very easily thank you so much Arvind sir (bhaiya)❤😂

[himanshuyadav]

Hats off sir, you explained each concept so well
Thank you sir 🙏

[mathmavericks]

With due respect to arvind sir...
Here i am pointing some nice approach for some question...
At 56:09 this problem can be solved using newton rule..in smart way and hope it will help some jee aspirant..
S²¹ -7S²⁰-S¹⁹=0
S²⁰-7S¹⁹-S¹⁸=0
S¹⁹-7S¹⁸-S¹⁷=0
NOW WE CAN OBSERVE WE DONT NEED S²⁰ and S¹8 and both can be eliminated by multipliyng 2 nd eqn by 7 and 3rd by -1and then adding all three.. we will get
S²¹-51S¹⁹+S¹⁷=0
SO S²¹+S¹⁷/S¹⁹=51

At 1:12:00
X²-X+1=0 Iske roots -w(omega) aur -w² honge inka cube krne pr inka value -1 hoga..he made a silly mistake so .bita ³= gama³=-1 put krdo

13:03 mene silly mistake ki...
16:16 - nazare!!! ❤️🔥
24:46 - me sq open krne me lgi thi....opt dekh ke idea lena chahiye tha ki root lelo
Warna sq open krne me, formula lgane me time lgta bht...
26:17
29:40 bade se cubic ya usse bhi bdi eqn dekr b coeff ka term nhi dete agar eqn me toh ams ko zero likhne me bht time consume hota
32:05 diff of roots ka magnitude isliye lete coz alpha 2 beta 3 hoskta ya ulta bhi. Ans ko toh frk nhi pdna chahiye na
32:55
37:30 worried abt mod, phir preshan hoti ki use kese hataye 😅

1:57:51 we can also substract the two equations, find the value of x in terms of a, then satisfy it in the given equation (if we want to avoid applying condition)

[anamaysinha]

2:58:44 sir Yana pe -7 bhi to include hoga. -4-2root3 is approx -7.46 which is less than the approx -6.9

[ArjunIITB.]

2:56:59 but sirr yaha, 1 and 2 interval mein included nahi hai, which means that on both 1 and 2 the expression will not give value negative, hence, the case which remains is that both should be the roots, then only the numbers lying between both of them give value negative and 1 and 2 themselves give 0.

bhai apki jo VJEE elite seires hai preapratio ke liye wo jyada achi rahegi ya phir jo aap ab one shots dal rahe ho wo ache rahege?

[esamriddharoy]

thank you sir really helped me a lot and i wish that you and all teachers stay healthy and happy😘😘

[hrikam]

Great session Sir! Thank you very much!

[abhinavjoshi]

Sir IS lecture ke notes telegram ke alava aur kahin nahin mil sakte kya.???.... Main telegram nahin join kar sakta Varna mere parents bahut please kuchh solution bata do

[DivyanshiDoraRoy]

Sir, can u please complete Linear Inequality; Relations and Functions and Basic Calculus for Class 11 by the 1st week of August as I have 1 test in the 2nd week of August which will include these topics. PLEASE SIR!!!

[Triggered_army]

sir ye video ko 11th students dekh sakte hai smajhne ke liye

[problemsolver]

Session was wonderful today there was my test in coaching and I did almost all questions of quadratic eqn and some of the question was as it is from lectures 🔥
But I only faced problem in location of roots

[sameepshukla]

1:52:44 sir in dono eqn mai hum agar lamda ko hi eliminate kar de fir x nikal kar bhi kar sakte hai na? Isse x =0, 1 aata hai aur 0 satisfy nhi karta thus 1 hi common root hoga isse lamda = -1 aa jaata hai.

[Hhjjchh]

Thanks bhai for such a beautiful and wonderful content for free
