If (q(x)=x-6+2x-4+3x-2+4), what type of powers does this polynomial have?
A. केवल सम घातेंOnly even powers
इसमें घातें (6), (4), (2) और (0) हैं। ये सभी सम और बहुपद के लिए मान्य हैं। / It has powers (6), (4), (2), and (0). All are even and valid for a polynomial.

Which expression is not a polynomial because it has power \(-\frac{1}{2}\) of (x)?
B. (x^{-12}+5)
\(-\frac{1}{2}\) न तो शून्य है और न धनात्मक पूर्णांक। इसलिए यह घात बहुपद में मान्य नहीं है। / \(-\frac{1}{2}\) is neither zero nor a positive integer. So this power is not valid in a polynomial.

Which expression is a polynomial in (x) if (b) is treated as a constant?
A. \(b x^4-3b x+2\)
(b) को (x) के संदर्भ में गुणांक माना जा सकता है। (x) की घातें (4), (1) और (0) हैं। / (b) can be treated as a coefficient with respect to (x). The powers of (x) are (4), (1), and (0).

Which statement is correct about \(x^3+x^2+x+1\)?
A. यह चार पदों वाला घन बहुपद हैIt is a cubic polynomial with four terms
इसमें चार पद हैं और सबसे बड़ी घात (3) है। इसलिए यह चार पदों वाला घन बहुपद है। / It has four terms and the highest power is (3). Therefore, it is a cubic polynomial with four terms.

Which expression is not a polynomial in (x) because it contains \(\tan x\)?
A. \(x^2+\tan x\)
बहुपद के पद चर की निश्चित शून्य या धनात्मक पूर्णांक घातों में होते हैं। \(\tan x\) ऐसा पद नहीं है। / Polynomial terms use fixed non-negative integer powers of the variable. \(\tan x\) is not such a term.

If (p(x)=5x-3+0x-2+0x-12), how many non-zero terms are there in (p(x))?
B. (2)
\(0x^2\) और (0x) शून्य पद हैं। अशून्य पद \(5x^3\) और (-12) हैं। / \(0x^2\) and (0x) are zero terms. The non-zero terms are \(5x^3\) and (-12).

Which expression is a polynomial in (x) but its constant term is not written?
A. \(4x^4-3x^2\)
\(4x^4-3x^2\) में कोई अलग स्थिर पद नहीं है, इसलिए स्थिर पद (0) माना जाता है। सभी घातें मान्य हैं। / In \(4x^4-3x^2\), there is no separate constant term, so the constant term is considered (0). All powers are valid.

Why is \(\frac{x^4+x^3}{x^2}\) not a polynomial after simplifying for \(x\neq0\)?
A. क्योंकि यह \(x^2+x\) बनता हैBecause it becomes \(x^2+x\)
\(\frac{x^4+x^3}{x^2}=x^2+x\) है। यह बहुपद है, इसलिए सही कारण यह है कि इसमें घातें (2) और (1) मान्य हैं। / \(\frac{x^4+x^3}{x^2}=x^2+x\). It is a polynomial, so the correct reason is that powers (2) and (1) are valid.

Which statement is correct about ((x+2)2)?
C. यह द्विघात बहुपद हैIt is a quadratic polynomial
विस्तारित रूप \(x^2+4x+4\) है। सबसे बड़ी घात (2) है, इसलिए यह द्विघात बहुपद है। / The expanded form is \(x^2+4x+4\). The highest power is (2), so it is a quadratic polynomial.

Which expression is a polynomial in (x) but is not written in descending powers?
A. \(5+x^3-2x\)
\(5+x^3-2x\) में घातें (0), (3), (1) हैं, पर सभी मान्य हैं। घटते क्रम में लिखना जरूरी नहीं है। / In \(5+x^3-2x\), the powers are (0), (3), and (1), but all are valid. Writing in descending order is not required.
