Jee nikale 3 saal hogye, mere homepage pe aise hi video aagyi aur mai dekhne lag pda.These questions and these logical concepts are just so interesting.
I'm emotional at the moment sir...I used to practice such kind of questions when I was in 12th... subsequently I decided not to pursue the dream of going into this line...due to some personal problems...I miss those days when I used to solve these problems with all my dedication. I got recommended a mathematical PYQ video after 5 years...I can't express in words how sorry I am for leaving this line
Nahi Bhai sochna pada tha yeh lawda insan hai isme sabse pehele neeche ka quadratic socha ki zero nhi hoskta toh uske cancell krdia fir sinx+2 zero nhi hoskta fir epix zeero nhi hoskta bas voh 2023 wala bacha usme -1 solution aya
Today I have completed my BE in ME from JU , still I am able to get a hang of this question ...I pick my copy n try to solve it ...may be this all what IIT JEE does to you ...Only one comment do cherish and enjoy the journey undertaken by all of you .

Sir I got admission into NIT nagpur in 2019 and I dropped out in 2020. 4 years later, today, RUclips randomly recommend this video, and it made me feel so happy, such an easy and understandable explanation, makes me wonder that I used to solve all such maths questions with ease a few years ago, now my brain is all rusty I can't even imagine doing calculus again.😅
*Denominators are equal and non-zero* (for real x). So, they can be cancelled without changing the problem. It's because { e^(πx) > 0 for all real x. x^2 - x + 3 has b^2 < 4ac so no real roots, and the expression is always positive, with minima at 2x - 1 = 0 or x = 1/2 so x^2 - x + 3 has min value of 3.25 - 0.5 = 2.75 }. (sin x + 2) is always positive (non-zero), so the problem can be simplified to - find number of real-roots of { x^2023 + 2024 x + 2025 } which again is a strictly positive function with negative values when x < -1 and strictly positive values when x > -1 (It's 0 at x = -1). Hence, for the overall problem, there is *only 1 real root which is x = -1*

I can understand your feelings.
It is the worst feeling that none can understand.
Very good question really tests your knowledge in a lot of concepts
Sir way of explaining proves why maths is so beautiful❤
Nostalgic stuff! Thank you sir.
Just passed our this year! :)
Best thing about sir is he considered all possibilities instead of just solving the question. ❤
Completed my btech now watching with passion thnx sir reminded me old days.
Well explained, anybody having basics level of understanding can understand this
Thanks
Sir your video made me nostalgic I gave exam back in 2017 now I feel old 😂😂
I gave the jee in 2008. You’re not that old 😂
Felt proud that i was able to solve this by looking at this and starting the way that what could not be negative. Really cool step by step explanation
Loved these types of questions. Analyzing functions and their behaviour. Some would say it's the best thing to do in Mathematics.
RUclips recommend this out of no where. It's been 7 years clearing JEE. Those were some days!!!
Easiest advance question, dekhte hi ho gya
Yep
Dekhte hi to nhi ho sakta kuch to karna hi padega solve , tukka mara h to aese hi bol de

Applying Descartes' rule of signs directly gives us the number of solutions for x is one.
Be cautious it also counts repeated root twice

Ye question un logo ko fasane ke liye tha jo question dekhte hi leave kar dete hai but it was easy
Can you explain it in more easy way
Isme to pen bhi nahi chalana pada tha 😅
x=-1 is the only solution .
Only real solution no?😊

So x=-1 is the "only" solution

😂 pura paper solve krke dekh!
Waha tu padhega bhi nhi poora 😂 and agge bhar jayega hard dekhte hi
The answer should be -1 right
Tukka sahi hua 😅
