किस मान पर (\(s^2-4\)x-9+(s-2)x-7+4) की डिग्री (0) होगी?
For which value will (\(s^2-4\)x-9+(s-2)x-7+4) have degree (0)?
Explanation opens after your attempt
A. (s=2)
Concept
For degree (0), both \(x^9\) and \(x^7\) terms must vanish. At (s=2), both coefficients become (0).
Why this answer is correct
The correct answer is A. (s=2). For degree (0), both \(x^9\) and \(x^7\) terms must vanish. At (s=2), both coefficients become (0).
Exam Tip
डिग्री (0) के लिए \(x^9\) और \(x^7\) दोनों पद हटने चाहिए। (s=2) पर दोनों गुणांक (0) हो जाते हैं।
