यदि (s=2), तो ((s-2)x-4+(s+1)x-3-5) की डिग्री क्या होगी?
If (s=2), what will be the degree of ((s-2)x-4+(s+1)x-3-5)?
Explanation opens after your attempt
B. (3)
Concept
Putting (s=2) makes the coefficient of \(x^4\) equal to (0) and the coefficient of \(x^3\) equal to (3). So the highest power is (3).
Why this answer is correct
The correct answer is B. (3). Putting (s=2) makes the coefficient of \(x^4\) equal to (0) and the coefficient of \(x^3\) equal to (3). So the highest power is (3).
Exam Tip
(s=2) रखने पर \(x^4\) का गुणांक (0) और \(x^3\) का गुणांक (3) हो जाता है। इसलिए सबसे बड़ी घात (3) है।
