कौन-सा व्यंजक (x) में बहुपद नहीं है, हालांकि उसमें केवल दो पद हैं?
Which expression is not a polynomial in (x), although it has only two terms?
Explanation opens after your attempt
C. \(x^{-1}+8\)
Concept
Having two terms does not guarantee being a polynomial. Due to the negative power \(x^{-1}\), it is not a polynomial.
Why this answer is correct
The correct answer is C. \(x^{-1}+8\). Having two terms does not guarantee being a polynomial. Due to the negative power \(x^{-1}\), it is not a polynomial.
Exam Tip
दो पद होना बहुपद होने की गारंटी नहीं है। \(x^{-1}\) की ऋणात्मक घात के कारण यह बहुपद नहीं है।
