किस मान पर ((w+5)x^{11}+\(w^2-25\)x-7+6x-4-2) की डिग्री (4) होगी?
For which value will ((w+5)x^{11}+\(w^2-25\)x-7+6x-4-2) have degree (4)?
Explanation opens after your attempt
B. (w=-5)
Concept
For degree (4), both \(x^{11}\) and \(x^7\) terms must vanish. At (w=-5), both coefficients become (0).
Why this answer is correct
The correct answer is B. (w=-5). For degree (4), both \(x^{11}\) and \(x^7\) terms must vanish. At (w=-5), both coefficients become (0).
Exam Tip
डिग्री (4) के लिए \(x^{11}\) और \(x^7\) दोनों पद हटने चाहिए। (w=-5) पर दोनों गुणांक (0) हो जाते हैं।
