Correct Answer

B. (w=-5)

Step 1

Concept

For degree (4), both \(x^{11}\) and \(x^7\) terms must vanish. At (w=-5), both coefficients become (0).

Step 2

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).

Step 3

Exam Tip

डिग्री (4) के लिए \(x^{11}\) और \(x^7\) दोनों पद हटने चाहिए। (w=-5) पर दोनों गुणांक (0) हो जाते हैं।
