यदि (q(x)=(k+2)2x^{11}+\(k^2-4\)x-6-5x-3+1) और (k=-2), तो (q(x)) की डिग्री क्या है?
If (q(x)=(k+2)2x^{11}+\(k^2-4\)x-6-5x-3+1) and (k=-2), what is the degree of (q(x))?
Explanation opens after your attempt
C. (3)
Concept
Putting (k=-2) removes both \(x^{11}\) and \(x^6\) terms. The remaining \(-5x^3+1\) has degree (3).
Why this answer is correct
The correct answer is C. (3). Putting (k=-2) removes both \(x^{11}\) and \(x^6\) terms. The remaining \(-5x^3+1\) has degree (3).
Exam Tip
(k=-2) रखने पर \(x^{11}\) और \(x^6\) दोनों पद हट जाते हैं। बचा \(-5x^3+1\) है जिसकी डिग्री (3) है।
