Which option correctly writes \(6x^3+0x^2-2x+9\) in simplified form?
A. \(6x^3-2x+9\)
\(0x^2\) का मान (0) है इसलिए वह पद हट जाता है। बाकी पद जैसे हैं वैसे रहते हैं। / The value of \(0x^2\) is (0), so that term vanishes. The remaining terms stay unchanged.

If (p(x)=x-2-3x+2), which statement about (p(1)) and (p(2)) is correct?
A. दोनों (0) हैंBoth are (0)
(p(1)=1-3+2=0) और (p(2)=4-6+2=0) है। इसलिए दोनों शून्य हैं। / (p(1)=1-3+2=0) and (p(2)=4-6+2=0). So both are zeros.

Which of the following polynomials does not have leading coefficient (1)?
C. \(3x^2+x+1\)
\(3x^2+x+1\) का प्रमुख पद \(3x^2\) है। इसका प्रमुख गुणांक (3) है, (1) नहीं। / The leading term of \(3x^2+x+1\) is \(3x^2\). Its leading coefficient is (3), not (1).

If (p(x)=2x-2+bx-10) and (p(2)=4), what is the value of (b)?
C. (3)
(p(2)=8+2b-10=4) से (2b-2=4) मिलता है। इसलिए (b=3) है। / (p(2)=8+2b-10=4) gives (2b-2=4). Therefore (b=3).

Which option correctly describes the type of \(x^3-1\)?
C. त्रिघात द्विपदीCubic binomial
\(x^3-1\) की घात (3) है और इसमें (2) पद हैं। इसलिए यह त्रिघात द्विपदी है। / \(x^3-1\) has degree (3) and (2) terms. So it is a cubic binomial.

If the constant term in (p(x)=x-2+5x+c) is (-6), what will (p(0)) be?
B. (-6)
(p(0)) हमेशा नियत पद के बराबर होता है। यहाँ नियत पद (-6) है। / (p(0)) is always equal to the constant term. Here the constant term is (-6).

Which of the following is a polynomial in (t)?
C. \(4t^3-\frac{1}{2}t+7\)
\(4t^3-\frac{1}{2}t+7\) में (t) की घातें (3), (1) और (0) हैं। ये सभी पूर्ण संख्याएँ हैं। / In \(4t^3-\frac{1}{2}t+7\), the powers of (t) are (3), (1), and (0). All are whole numbers.

If (p(x)=x-2-2x+3), what is the value of (p(2)+p(-1))?
B. (9)
(p(2)=3) और (p(-1)=6) है। इसलिए योग (9) है। / (p(2)=3) and (p(-1)=6). Therefore the sum is (9).

If \(a\neq0\), which statement is correct about (ax+b)?
B. यह रैखिक बहुपद हैIt is a linear polynomial
\(a\neq0\) होने पर (x) का पद मौजूद रहता है। इसलिए (ax+b) की घात (1) होती है। / When \(a\neq0\), the (x)-term is present. So (ax+b) has degree (1).

In \(2x^4+3x^2-5x+7\), what is the sum of the coefficient of \(x^3\) and the coefficient of (x)?
A. (-5)
\(x^3\) का गुणांक (0) और (x) का गुणांक (-5) है। योग (-5) है। / The coefficient of \(x^3\) is (0) and the coefficient of (x) is (-5). The sum is (-5).
