यदि (n=-2), तो (\(n^2-4\)x-6+(n+5)x-3-7) की डिग्री क्या होगी?

If (n=-2), what will be the degree of (\(n^2-4\)x-6+(n+5)x-3-7)?

Explanation opens after your attempt
Correct Answer

B. (3)

Step 1

Concept

Putting (n=-2), the coefficient of \(x^6\) is (0) and the coefficient of \(x^3\) is (3). Therefore the degree is (3).

Step 2

Why this answer is correct

The correct answer is B. (3). Putting (n=-2), the coefficient of \(x^6\) is (0) and the coefficient of \(x^3\) is (3). Therefore the degree is (3).

Step 3

Exam Tip

(n=-2) रखने पर \(x^6\) का गुणांक (0) और \(x^3\) का गुणांक (3) होता है। इसलिए डिग्री (3) है।
