यदि (p(x)=\(a^2-1\)x^{10}+(a-1)x-6+2x-3-4) की डिग्री (3) है, तो (a) का सही मान कौन सा है?
If the degree of (p(x)=\(a^2-1\)x^{10}+(a-1)x-6+2x-3-4) is (3), which value of (a) is correct?
Explanation opens after your attempt
C. (a=1)
Concept
For degree (3), the \(x^{10}\) and \(x^6\) terms must vanish. At (a=1), both higher-term coefficients become (0).
Why this answer is correct
The correct answer is C. (a=1). For degree (3), the \(x^{10}\) and \(x^6\) terms must vanish. At (a=1), both higher-term coefficients become (0).
Exam Tip
डिग्री (3) के लिए \(x^{10}\) और \(x^6\) के पद हटने चाहिए। (a=1) पर दोनों उच्च पदों के गुणांक (0) हो जाते हैं।
