यदि (u=-2), तो ((u+2)x-5+\(u^2-1\)x-4+x) की डिग्री क्या है?

If (u=-2), what is the degree of ((u+2)x-5+\(u^2-1\)x-4+x)?

Explanation opens after your attempt
Correct Answer

B. (4)

Step 1

Concept

At (u=-2), the coefficient of \(x^5\) is (0) and the coefficient of \(x^4\) is (3). Therefore the degree is (4).

Step 2

Why this answer is correct

The correct answer is B. (4). At (u=-2), the coefficient of \(x^5\) is (0) and the coefficient of \(x^4\) is (3). Therefore the degree is (4).

Step 3

Exam Tip

(u=-2) पर \(x^5\) का गुणांक (0) और \(x^4\) का गुणांक (3) होता है। इसलिए डिग्री (4) है।
