यदि (k=2), तो ((k-2)x-5+3x-2-1) की डिग्री क्या होगी?
If (k=2), what will be the degree of ((k-2)x-5+3x-2-1)?
Explanation opens after your attempt
C. (2)
Concept
Putting (k=2) makes the coefficient of \(x^5\) equal to (0). The remaining highest power is (2).
Why this answer is correct
The correct answer is C. (2). Putting (k=2) makes the coefficient of \(x^5\) equal to (0). The remaining highest power is (2).
Exam Tip
(k=2) रखने पर \(x^5\) का गुणांक (0) हो जाता है। बची हुई सबसे बड़ी घात (2) है।
