यदि (p(x)=(a+6)x^{13}+\(a^2-36\)x-9+4x-4-2) की डिग्री (4) है, तो (a) का सही मान कौन सा है?

If the degree of (p(x)=(a+6)x^{13}+\(a^2-36\)x-9+4x-4-2) is (4), which value of (a) is correct?

Correct Answer

A. (a=-6)

Step 1

Concept

For degree (4), both \(x^{13}\) and \(x^9\) terms must vanish. At (a=-6), both higher-term coefficients become (0).

Step 2

Why this answer is correct

The correct answer is A. (a=-6). For degree (4), both \(x^{13}\) and \(x^9\) terms must vanish. At (a=-6), both higher-term coefficients become (0).

Step 3

Exam Tip

डिग्री (4) के लिए \(x^{13}\) और \(x^9\) दोनों पद हटने चाहिए। (a=-6) पर दोनों उच्च पदों के गुणांक (0) हो जाते हैं।
