यदि \(b\neq-2\), तो ((b+2)x^{12}+5x-6-4) की डिग्री क्या होगी?
If \(b\neq-2\), what will be the degree of ((b+2)x^{12}+5x-6-4)?
Explanation opens after your attempt
B. (12)
Concept
When \(b\neq-2\), the coefficient of \(x^{12}\) is not zero. Therefore the highest power remains (12).
Why this answer is correct
The correct answer is B. (12). When \(b\neq-2\), the coefficient of \(x^{12}\) is not zero. Therefore the highest power remains (12).
Exam Tip
\(b\neq-2\) होने पर \(x^{12}\) का गुणांक शून्य नहीं है। इसलिए सबसे बड़ी घात (12) रहेगी।
