यदि (p(x)=(a-5)x^{12}+\(a^2-25\)x-8+7x-2-3) की डिग्री (2) है, तो (a) का सही मान कौन सा है?
If the degree of (p(x)=(a-5)x^{12}+\(a^2-25\)x-8+7x-2-3) is (2), which value of (a) is correct?
Explanation opens after your attempt
A. (a=5)
Concept
For degree (2), both \(x^{12}\) and \(x^8\) terms must vanish. At (a=5), both higher-term coefficients become (0).
Why this answer is correct
The correct answer is A. (a=5). For degree (2), both \(x^{12}\) and \(x^8\) terms must vanish. At (a=5), both higher-term coefficients become (0).
Exam Tip
डिग्री (2) के लिए \(x^{12}\) और \(x^8\) दोनों पद हटने चाहिए। (a=5) पर दोनों उच्च पदों के गुणांक (0) हो जाते हैं।
