What is the expression \(2x^2+\sqrt{7}x-3\)?
A. बहुपदPolynomial
\(\sqrt{7}\) वास्तविक गुणांक है और (x) की घात (1) है। इसलिए यह बहुपद है। / \(\sqrt{7}\) is a real coefficient and the power of (x) is (1). Therefore it is a polynomial.

What is the expression \(4x+\sqrt{x}\)?
C. बहुपद नहींNot a polynomial
\(\sqrt{x}=x^{\frac{1}{2}}\) होता है। भिन्न घात के कारण यह बहुपद नहीं है। / \(\sqrt{x}=x^{\frac{1}{2}}\). Due to the fractional power, it is not a polynomial.

What is the constant term in the polynomial \(11x^3\)?
C. (0)
इस बहुपद में बिना चर वाला पद नहीं है। इसलिए नियतांक पद (0) माना जाता है। / This polynomial has no term without a variable. So the constant term is taken as (0).

What is the coefficient of \(x^6\) in \(x^7+x^4+x\)?
D. (0)
इस बहुपद में \(x^6\) पद नहीं है। इसलिए \(x^6\) का गुणांक (0) है। / The \(x^6\) term is not present in this polynomial. So the coefficient of \(x^6\) is (0).

A. हां, क्योंकि \(x^0=1\) और (x) की घात (1) हैYes, because \(x^0=1\) and the power of (x) is (1)
\(x^0\) की घात (0) है जो बहुपद में मान्य है। इसलिए यह बहुपद है। / The power in \(x^0\) is (0), which is valid in a polynomial. Therefore it is a polynomial.

Is \(\frac{7x}{3}+4\) a polynomial in (x)?
B. हां, क्योंकि (x) की घात (1) हैYes, because the power of (x) is (1)
\(\frac{7x}{3}\) में (x) की घात (1) है और गुणांक \(\frac{7}{3}\) है। भिन्न गुणांक मान्य है। / In \(\frac{7x}{3}\), the power of (x) is (1) and the coefficient is \(\frac{7}{3}\). A fractional coefficient is valid.

Is \(-\frac{5}{6}x^2+x-8\) a polynomial?
A. हां, क्योंकि गुणांक वास्तविक हैं और घातें मान्य हैंYes, because coefficients are real and powers are valid
गुणांक ऋणात्मक या भिन्न हो सकते हैं। यहां (x) की घातें (2), (1), और (0) हैं। / Coefficients can be negative or fractional. Here the powers of (x) are (2), (1), and (0).

Which expression is not a polynomial because the variable has power \(\frac{3}{4}\)?
B. \(x^{\frac{3}{4}}+2\)
\(\frac{3}{4}\) भिन्न घात है। बहुपद में चर की घात पूर्ण संख्या होनी चाहिए। / \(\frac{3}{4}\) is a fractional power. In a polynomial, the variable power must be a whole number.
