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
Correct Answer

C. (2)

Step 1

Concept

Putting (k=2) makes the coefficient of \(x^5\) equal to (0). The remaining highest power is (2).

Step 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).

Step 3

Exam Tip

(k=2) रखने पर \(x^5\) का गुणांक (0) हो जाता है। बची हुई सबसे बड़ी घात (2) है।
