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
Correct Answer

C. (1)

Step 1

Concept

For (z=-2), the coefficients of both \(x^5\) and \(x^3\) become (0). The remaining highest power is (1).

Step 2

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).

Step 3

Exam Tip

(z=-2) पर \(x^5\) और \(x^3\) दोनों के गुणांक (0) हो जाते हैं। बची हुई सबसे बड़ी घात (1) है।
