यदि ((c+4)x-7+\(c^2-16\)x-5+21) की डिग्री (0) है, तो (c) का मान क्या है?
If the degree of ((c+4)x-7+\(c^2-16\)x-5+21) is (0), what is the value of (c)?
Explanation opens after your attempt
B. (c=-4)
Concept
For degree (0), both \(x^7\) and \(x^5\) terms must vanish. At (c=-4), both coefficients become (0).
Why this answer is correct
The correct answer is B. (c=-4). For degree (0), both \(x^7\) and \(x^5\) terms must vanish. At (c=-4), both coefficients become (0).
Exam Tip
डिग्री (0) के लिए \(x^7\) और \(x^5\) दोनों पद हटने चाहिए। (c=-4) पर दोनों गुणांक (0) हो जाते हैं।
