यदि (z=-2), तो ((z+2)x-5+\(z^2-4\)x-3+9x-1) की डिग्री क्या होगी?
If (z=-2), what will be the degree of ((z+2)x-5+\(z^2-4\)x-3+9x-1)?
Explanation opens after your attempt
C. (1)
Concept
For (z=-2), the coefficients of both \(x^5\) and \(x^3\) become (0). The remaining highest power is (1).
Why this answer is correct
The correct answer is C. (1). For (z=-2), the coefficients of both \(x^5\) and \(x^3\) become (0). The remaining highest power is (1).
Exam Tip
(z=-2) पर \(x^5\) और \(x^3\) दोनों के गुणांक (0) हो जाते हैं। बची हुई सबसे बड़ी घात (1) है।
