यदि (c=0), तो (cx-8+(c+2)x-5-4x+1) की डिग्री क्या होगी?
If (c=0), what will be the degree of (cx-8+(c+2)x-5-4x+1)?
Explanation opens after your attempt
B. (5)
Concept
For (c=0), the \(x^8\) term disappears and the coefficient of \(x^5\) remains (2). Therefore the degree is (5).
Why this answer is correct
The correct answer is B. (5). For (c=0), the \(x^8\) term disappears and the coefficient of \(x^5\) remains (2). Therefore the degree is (5).
Exam Tip
(c=0) पर \(x^8\) पद हट जाता है और \(x^5\) का गुणांक (2) रहता है। इसलिए डिग्री (5) है।
