Which option is a polynomial in one variable but not linear?
B. \(x^2+2x+3\)
\(x^2+2x+3\) बहुपद है और इसकी घात (2) है। इसलिए यह रैखिक नहीं है। / \(x^2+2x+3\) is a polynomial and its degree is (2). Therefore it is not linear.

What is the zero of (p(x)=9x-27)?
B. (3)
(9x-27=0) से (x=3) मिलता है। रैखिक बहुपद का शून्य समीकरण हल करके निकालें। / From (9x-27=0), we get (x=3). Find the zero of a linear polynomial by solving the equation.

Which is the zero of (p(x)=4x+20)?
B. (-5)
(4x+20=0) से (x=-5) मिलता है। शून्य वह मान है जिससे बहुपद (0) हो जाए। / From (4x+20=0), we get (x=-5). A zero is the value that makes the polynomial equal to (0).

If (p(x)=cx+d) and \(c\ne0\), what will be its zero?
B. \(-\frac{d}{c}\)
(cx+d=0) से \(x=-\frac{d}{c}\) मिलता है। सूत्र में ऋण चिह्न ध्यान रखें। / From (cx+d=0), we get \(x=-\frac{d}{c}\). Remember the negative sign in the formula.

What is the coefficient of \(x^2\) in (p(x)=5x-3+0x-2-4x+12)?
A. (0)
\(x^2\) वाला पद \(0x^2\) है इसलिए गुणांक (0) है। अनुपस्थित या शून्य पद का गुणांक (0) माना जाता है। / The \(x^2\)-term is \(0x^2\), so the coefficient is (0). A missing or zero term has coefficient (0).

Which power is missing in (p(x)=x-5+3x-3-2)?
B. \(x^4\)
इस बहुपद में \(x^4\) का पद नहीं है। अनुपस्थित पद का गुणांक (0) होता है। / The term \(x^4\) is not present in this polynomial. A missing term has coefficient (0).

What should the powers of the variable be in a polynomial in one variable?
C. अऋणात्मक पूर्णांकNon-negative integers
बहुपद में चर की घातें \(0,1,2,\ldots\) जैसी अऋणात्मक पूर्णांक होती हैं। यही बहुपद की मूल पहचान है। / In a polynomial, powers of the variable are non-negative integers like \(0,1,2,\ldots\). This is the basic identification rule.

For (p(x)=x-2-8x+13), what is (p(0))?
C. (13)
(p(0)=0-0+13=13)। (x=0) रखने पर अचर पद ही बचता है। / (p(0)=0-0+13=13). When (x=0), only the constant term remains.

What is the value of (p\left\(\frac{2}{3}\right\)) for (p(x)=9x-2-12x+4)?
A. (0)
(p\left\(\frac{2}{3}\right\)=9\cdot\frac{4}{9}-8+4=0)। भिन्न मान रखते समय वर्ग और गुणा सावधानी से करें। / (p\left\(\frac{2}{3}\right\)=9\cdot\frac{4}{9}-8+4=0). While substituting a fraction, square and multiply carefully.

What is the coefficient of \(x^3\) in (p(x)=7x-4-2x-2+9)?
C. (0)
\(x^3\) का पद उपस्थित नहीं है इसलिए उसका गुणांक (0) है। अनुपस्थित पद को \(0x^3\) समझें। / There is no \(x^3\)-term, so its coefficient is (0). Treat the missing term as \(0x^3\).
