यदि (q(x)=\(k^2-9\)x-6+(k-3)x-4+2x-2) और (k=3), तो (q(x)) की डिग्री क्या है?
If (q(x)=\(k^2-9\)x-6+(k-3)x-4+2x-2) and (k=3), what is the degree of (q(x))?
Explanation opens after your attempt
D. (2)
Concept
At (k=3), both \(x^6\) and \(x^4\) terms vanish. The remaining highest power is (2).
Why this answer is correct
The correct answer is D. (2). At (k=3), both \(x^6\) and \(x^4\) terms vanish. The remaining highest power is (2).
Exam Tip
(k=3) पर \(x^6\) और \(x^4\) दोनों पद हट जाते हैं। बची हुई सबसे बड़ी घात (2) है।
