Explanation opens after your attempt
Correct Answer

A. (u=7)

Step 1

Concept

For degree (0), both \(x^{10}\) and \(x^4\) terms must vanish. At (u=7), both coefficients are (0).

Step 2

Why this answer is correct

The correct answer is A. (u=7). For degree (0), both \(x^{10}\) and \(x^4\) terms must vanish. At (u=7), both coefficients are (0).

Step 3

Exam Tip

डिग्री (0) के लिए \(x^{10}\) और \(x^4\) दोनों पद हटने चाहिए। (u=7) पर दोनों गुणांक (0) हैं।
