यदि (n=1), तो (\(n^2-1\)x-4+(n+2)x-2-6) की डिग्री क्या होगी?
If (n=1), what will be the degree of (\(n^2-1\)x-4+(n+2)x-2-6)?
Explanation opens after your attempt
C. (2)
Concept
Putting (n=1), the coefficient of \(x^4\) is (0) and the coefficient of \(x^2\) is (3). Therefore the degree is (2).
Why this answer is correct
The correct answer is C. (2). Putting (n=1), the coefficient of \(x^4\) is (0) and the coefficient of \(x^2\) is (3). Therefore the degree is (2).
Exam Tip
(n=1) रखने पर \(x^4\) का गुणांक (0) और \(x^2\) का गुणांक (3) होता है। इसलिए डिग्री (2) है।
