Concept
For degree (3), the \(x^5\) term must vanish and the \(x^3\) term must remain. This is true at (d=-2).
Why this answer is correct
The correct answer is B. (d=-2). For degree (3), the \(x^5\) term must vanish and the \(x^3\) term must remain. This is true at (d=-2).
Exam Tip
डिग्री (3) के लिए \(x^5\) पद हटना चाहिए और \(x^3\) पद बचना चाहिए। (d=-2) पर यह सही होता है।
