किस विकल्प में बहुपद की डिग्री (7) है और \(x^6\) का गुणांक (0) है?
Which option has degree (7) and coefficient of \(x^6\) equal to (0)?
Explanation opens after your attempt
A. \(3x^7-2x^5+1\)
Concept
The first polynomial has degree (7), and the \(x^6\) term is absent. So the coefficient of \(x^6\) is (0).
Why this answer is correct
The correct answer is A. \(3x^7-2x^5+1\). The first polynomial has degree (7), and the \(x^6\) term is absent. So the coefficient of \(x^6\) is (0).
Exam Tip
पहले बहुपद की डिग्री (7) है और \(x^6\) पद अनुपस्थित है। इसलिए \(x^6\) का गुणांक (0) है।
