Which is a constant polynomial?
A. (6)
जिस बहुपद में चर नहीं होता वह नियत बहुपद है। (6) में (x) नहीं है। / A polynomial with no variable is a constant polynomial. (6) has no (x).

In (p(x)=ax+b), if \(a\ne0\), what is its degree?
B. (1)
\(a\ne0\) होने पर (x) वाला पद मौजूद है, इसलिए घात (1) है। यही रैखिक बहुपद का रूप है। / When \(a\ne0\), the (x)-term exists, so the degree is (1). This is the form of a linear polynomial.

In (p(x)=ax-2+bx+c), if \(a\ne0\), what type of polynomial is it?
B. द्विघातQuadratic
\(a\ne0\) होने से \(x^2\) पद रहता है, इसलिए घात (2) है। घात (2) वाला बहुपद द्विघात होता है। / Since \(a\ne0\), the \(x^2\)-term remains, so the degree is (2). A degree (2) polynomial is quadratic.

What is the leading term of (p(x)=x-3+2x-2+x)?
A. \(x^3\)
सबसे बड़ी घात वाला पद \(x^3\) है। अग्र पद पहचानने के लिए सबसे बड़ी घात देखें। / The term with the highest power is \(x^3\). To identify the leading term, look for the highest power.

What conclusion follows when (x=2) is substituted in (p(x)=4x-8)?
A. (2) शून्यक है(2) is a zero
(p(2)=4\cdot2-8=0), इसलिए (2) शून्यक है। शून्यक जांचने के लिए मान (0) आना चाहिए। / (p(2)=4\cdot2-8=0), so (2) is a zero. To test a zero, the value must be (0).

In which option is the power of (x) acceptable for a polynomial?
C. \(x^0\)
बहुपद में (x) की घात \(0,1,2,\ldots\) जैसी होनी चाहिए। \(x^0\) स्वीकार्य है। / In a polynomial, powers of (x) must be \(0,1,2,\ldots\). \(x^0\) is acceptable.

When (x=0) is put in \(3x^2+2x+1\), which term remains?
C. (1)
(x=0) पर \(3x^2\) और (2x) शून्य हो जाते हैं। केवल नियत पद (1) बचता है। / At (x=0), \(3x^2\) and (2x) become zero. Only the constant term (1) remains.

If a polynomial has degree (1), what is it called?
B. रैखिक बहुपदLinear polynomial
घात (1) वाले बहुपद को रैखिक बहुपद कहते हैं। नाम हमेशा घात से जोड़कर याद करें। / A polynomial of degree (1) is called a linear polynomial. Link the name with the degree.

If a polynomial has degree (2), what is it called?
B. द्विघात बहुपदQuadratic polynomial
घात (2) वाला बहुपद द्विघात कहलाता है। \(x^2\) का अशून्य पद होना जरूरी है। / A degree (2) polynomial is called quadratic. A non-zero \(x^2\)-term must be present.
