किस मान पर (\(s^2-25\)x^{12}+(s+5)x-8+9) की डिग्री (0) होगी?

For which value will (\(s^2-25\)x^{12}+(s+5)x-8+9) have degree (0)?

Explanation opens after your attempt
Correct Answer

B. (s=-5)

Step 1

Concept

For degree (0), both \(x^{12}\) and \(x^8\) terms must vanish. At (s=-5), both coefficients become (0).

Step 2

Why this answer is correct

The correct answer is B. (s=-5). For degree (0), both \(x^{12}\) and \(x^8\) terms must vanish. At (s=-5), both coefficients become (0).

Step 3

Exam Tip

डिग्री (0) के लिए \(x^{12}\) और \(x^8\) दोनों पद हटने चाहिए। (s=-5) पर दोनों गुणांक (0) हो जाते हैं।
