किस मान पर ((d-1)x-4+(d+3)x-2+6) की डिग्री (2) होगी?
For which value will the degree of ((d-1)x-4+(d+3)x-2+6) be (2)?
Explanation opens after your attempt
A. (d=1)
Concept
For degree (2), the \(x^4\) term must vanish and the \(x^2\) term must remain. This is true at (d=1).
Why this answer is correct
The correct answer is A. (d=1). For degree (2), the \(x^4\) term must vanish and the \(x^2\) term must remain. This is true at (d=1).
Exam Tip
डिग्री (2) के लिए \(x^4\) पद हटना चाहिए और \(x^2\) पद बचना चाहिए। (d=1) पर यह सही होता है।
