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.
@cutedemon43Ай бұрын
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

Sir I got admission into NIT nagpur in 2019 and I dropped out in 2020. 4 years later, today, KZbin 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*
