For which value will the degree of ((d-6)x-7+(d+1)x-5+14) be (5)?
Explanation opens after your attempt
B. (d=6)
Concept
For degree (5), the \(x^7\) term must vanish and the \(x^5\) term must remain. This condition holds at (d=6).
Why this answer is correct
The correct answer is B. (d=6). For degree (5), the \(x^7\) term must vanish and the \(x^5\) term must remain. This condition holds at (d=6).
Exam Tip
डिग्री (5) के लिए \(x^7\) पद हटना चाहिए और \(x^5\) पद बचना चाहिए। (d=6) पर यह शर्त पूरी होती है।
