Explanation opens after your attempt
Correct Answer
B. यह बहुपद नहीं है क्योंकि \(x^{-2}\) हैIt is not a polynomial because it has \(x^{-2}\)
Concept
\(x^0\) is valid, but \(x^{-2}\) is invalid. Negative powers are not allowed in a polynomial.
Why this answer is correct
The correct answer is B. यह बहुपद नहीं है क्योंकि \(x^{-2}\) है / It is not a polynomial because it has \(x^{-2}\). \(x^0\) is valid, but \(x^{-2}\) is invalid. Negative powers are not allowed in a polynomial.
Exam Tip
\(x^0\) मान्य है, लेकिन \(x^{-2}\) अमान्य है। बहुपद में ऋणात्मक घात स्वीकार्य नहीं होती।
