यदि (c=0), तो (cx-5+(c+1)x-4-3x+2) की डिग्री क्या होगी?

If (c=0), what will be the degree of (cx-5+(c+1)x-4-3x+2)?

Explanation opens after your attempt
Correct Answer

B. (4)

Step 1

Concept

When (c=0), the \(x^5\) term disappears and the coefficient of \(x^4\) remains (1). Therefore the degree is (4).

Step 2

Why this answer is correct

The correct answer is B. (4). When (c=0), the \(x^5\) term disappears and the coefficient of \(x^4\) remains (1). Therefore the degree is (4).

Step 3

Exam Tip

(c=0) होने पर \(x^5\) पद हट जाता है और \(x^4\) का गुणांक (1) रहता है। इसलिए डिग्री (4) है।
