यदि (p(x)=(a-3)x-6+2x-2-1) और (a=3), तो (p(x)) की डिग्री क्या है?
If (p(x)=(a-3)x-6+2x-2-1) and (a=3), what is the degree of (p(x))?
Explanation opens after your attempt
C. (2)
Concept
Putting (a=3) makes the coefficient of \(x^6\) equal to (0). The remaining highest power is (2).
Why this answer is correct
The correct answer is C. (2). Putting (a=3) makes the coefficient of \(x^6\) equal to (0). The remaining highest power is (2).
Exam Tip
(a=3) रखने पर \(x^6\) का गुणांक (0) हो जाता है। बची हुई सबसे बड़ी घात (2) है।
