यदि (p(x)=(a-2)x-4+5x-2-3) में (a=2), तो (p(x)) की घात क्या होगी?
If (a=2) in (p(x)=(a-2)x-4+5x-2-3), what will be the degree of (p(x))?
Explanation opens after your attempt
C. (2)
Concept
At (a=2), the coefficient of \(x^4\) becomes (0). Therefore, the highest remaining power is (2).
Why this answer is correct
The correct answer is C. (2). At (a=2), the coefficient of \(x^4\) becomes (0). Therefore, the highest remaining power is (2).
Exam Tip
(a=2) पर \(x^4\) का गुणांक (0) हो जाता है। इसलिए सबसे बड़ी बची घात (2) है।
