यदि (k=-3), तो ((k+3)x-6+2x-2+x-7) की डिग्री क्या होगी?

If (k=-3), what will be the degree of ((k+3)x-6+2x-2+x-7)?

Explanation opens after your attempt
Correct Answer

A. (2)

Step 1

Concept

Putting (k=-3) makes the coefficient of \(x^6\) equal to (0). In the remaining polynomial, the highest power is (2).

Step 2

Why this answer is correct

The correct answer is A. (2). Putting (k=-3) makes the coefficient of \(x^6\) equal to (0). In the remaining polynomial, the highest power is (2).

Step 3

Exam Tip

(k=-3) रखने पर \(x^6\) का गुणांक (0) हो जाता है। शेष बहुपद में सबसे बड़ी घात (2) है।
