Let alpha and beta are the real roots of quadratic Equation with real coefficient x²+ax+b=0 and satisfies |alpha + a|+|beta + a| less than equal to 1 then find the maximum and minimum value of (a²+2b)
Mam I don't know how to thank u..I really wanna say I'm lucky to find u nd I'm enjoying all ur hilarious tricks for my jan exam. thank u very much mam😇
Maam aap koi bhi number let kr le rhi hai (1,2,3,....) But hum log ko kaise pta chlega ki kha pe kise let krna hai ....maam please help Thanks for fruitful trick☺️☺️

option B
I took λ=1 and solved using properties of det and i got the answer easily.
We need some more tricks like this. Thanks ma'am.
Q5. Answer is option(B)
By putting a=1, b=2, c=3, lemda=1
Given in question is an Identity in terms of a,b,c, lemda so LHS=RHS for any of their values
B is the right answer... for easy method u can take a=1, b=-1, c=0
Thanks..🙂 btw.. lambda ko value assign Nahi karna hai?
@@khushigangwar2792 but usne lambda ki value nahi a,b,c, inki ki hai
@@archanakirasoi2103 fine..👍✅
@@khushigangwar2792 mera abhi bhi solve nhi ho rha plzz help
by substituting as above, i get (lambda+1)^2= k70....the how do we solve further?
Mam I don't know how to thank u..I really wanna say I'm lucky to find u nd I'm enjoying all ur hilarious tricks for my jan exam. thank u very much mam😇

Hi
Mam we need more tricks like this !!! This just left me speechless 💓💓💓
B is the desired answer for last question....
I have taken, a=1,b=2,c=3,lambda=4!! And got the answer as B
take a=1,b =2,c =3,lambda =1
answer =4(lambda )^2
Very very.......... (infinity) Thank you very much. & yes we need this kind of tricks video 😇😇🤗

Thanku mam your tricks are very useful ❤️🙇🙇
Mam ur videos is more helpful,and iam execpting more videos from u
Options B by taking a=0, b=1 & c=2
B is answer for last one..(a=1,b=-1,c=2)
Thank you ma'am for this video
B=1 se kyuu nhi aa rha answer
@Gaurav Rajput.... If b=1 then the determinant of RHS with lambda will become zero as two columns will become same.
Thank you Mam
Please continue this series
Option b is the right answer then put a=0, b=1, c=2
For question 3, 9:07 I took the values x=3, y=5 then answer nai aara. How will we get to know answer kya hain 😑
It's based upon ur guess
We really need this type of trick....n lot of thanks for this mam☺️
Mam in 2nd question of a,b,c
The ∆1+∆2= 0 but you have taken
∆1=∆2 and ams should be even integer
Bhai b(a+c)≠0 hai dobara check karo
There is Δ1=-Δ2 not Δ1=Δ2
And if you take odd and will be -2
Thanks a lot mam.....u made it so easy😀
Mam can you explain me how to take the value of a b and c.
Wowwwww maammm it's really fabbbbbb
Bingoooooooo! Option (B) is the correct answer:-D
7:37 maam if we take a= b=c=1 then the final comes as "n" is an even integer .
no then also u will get n as odd only.... because i tried by taking a b c as 1
a=1 b=-1 c=0 lambda= 1 option B is correct
Putting a=1 b=2 c=3 and other one lambda =1
Thanks for this video ma'am. .
(B) 4*lambda^2
Option b is correct
Take a=0, b=-1, c= 1
Mam answer is "B"
And thanks for making excellent and marvellous videos for us.
Keep going like this.
We are with you😉😉😉😉😉
How!??!
What how disha???
Yrr mujhe bhi batao
Once try your self
Option B is correct

Ma'am option (B)
Put a=b=c=1👍👍
Mam B is the answer if a=1 b=-1 c=0
