What conclusion follows when (x=1) is substituted in (p(x)=2x-2-3x+1)?
A. (1) शून्य है(1) is a zero
(p(1)=2-3+1=0), इसलिए (1) शून्य है। शून्य के लिए परिणाम (0) होना चाहिए। / (p(1)=2-3+1=0), so (1) is a zero. For a zero, the result must be (0).

Which option is a polynomial in one variable but not quadratic?
B. \(4x^3+x-9\)
\(4x^3+x-9\) बहुपद है और इसकी घात (3) है। इसलिए यह द्विघात नहीं है। / \(4x^3+x-9\) is a polynomial and its degree is (3). Therefore it is not quadratic.

What is the zero of (p(x)=7x-14)?
B. (2)
(7x-14=0) से (x=2) मिलता है। रैखिक बहुपद का शून्य जल्दी निकालने के लिए समीकरण हल करें। / From (7x-14=0), we get (x=2). Solve the equation to find the zero of a linear polynomial.

Which is the zero of (p(x)=3x+12)?
B. (-4)
(3x+12=0) से (x=-4) मिलता है। शून्य वह मान है जिससे बहुपद (0) हो जाए। / From (3x+12=0), we get (x=-4). A zero is the value that makes the polynomial equal to (0).

If (p(x)=ax+b) and \(a\ne0\), what will be its zero?
B. \(-\frac{b}{a}\)
(ax+b=0) से \(x=-\frac{b}{a}\) मिलता है। सामान्य सूत्र याद रखें लेकिन संकेत न भूलें। / From (ax+b=0), we get \(x=-\frac{b}{a}\). Remember the general formula but do not miss the sign.

What is the coefficient of (x) in (p(x)=2x-2+0x+3)?
A. (0)
(x) वाला पद (0x) है इसलिए (x) का गुणांक (0) है। अनुपस्थित पद का गुणांक (0) मानें। / The (x)-term is (0x), so the coefficient of (x) is (0). Treat a missing term as having coefficient (0).

Which power is missing in (p(x)=x-4+2x-2+1)?
B. \(x^3\)
इस बहुपद में \(x^3\) का पद नहीं है। अनुपस्थित पद का गुणांक (0) होता है। / The term \(x^3\) is not present in this polynomial. A missing term has coefficient (0).

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

Which of the following is not a polynomial in one variable?
C. \(x^2+y+1\)
\(x^2+y+1\) में दो चर (x) और (y) हैं। इसलिए यह एक चर वाला बहुपद नहीं है। / \(x^2+y+1\) has two variables (x) and (y). Therefore it is not a polynomial in one variable.
