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
A. (2)
Concept
Putting (k=-3) makes the coefficient of \(x^6\) equal to (0). In the remaining polynomial, the highest power is (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).
Exam Tip
(k=-3) रखने पर \(x^6\) का गुणांक (0) हो जाता है। शेष बहुपद में सबसे बड़ी घात (2) है।
