For (p(x)=x-3-1), what is the value of (p(1))?
A. (0)
(p(1)=13-1=0)। परीक्षा में सीधे (x=1) रखकर मान निकालें। / (p(1)=13-1=0). In exams, substitute (x=1) directly to find the value.

Which expression is a polynomial in (x)?
B. \(x^2+\frac{1}{3}x+2\)
\(x^2+\frac{1}{3}x+2\) में (x) की घातें (2), (1) और (0) हैं। इसलिए यह बहुपद है। / In \(x^2+\frac{1}{3}x+2\), the powers of (x) are (2), (1), and (0). So it is a polynomial.

What is the coefficient of \(x^2\) in (p(x)=2x-4-5x-3+x-8)?
D. (0)
इस बहुपद में \(x^2\) पद नहीं है। इसलिए \(x^2\) का गुणांक (0) है। / There is no \(x^2\) term in this polynomial. Therefore the coefficient of \(x^2\) is (0).

If (p(x)=x-2-4), what is the value of (p(3))?
B. (5)
(p(3)=32-4=5)। परीक्षा में पहले घात का मान निकालें फिर घटाएं। / (p(3)=32-4=5). In exams, first evaluate the power and then subtract.

Which polynomial in (x) has degree (0)?
A. (12)
(12) शून्य से भिन्न स्थिर बहुपद है और इसकी घात (0) है। (0) बहुपद की घात परिभाषित नहीं होती। / The number (12) is a non-zero constant polynomial and its degree is (0). The degree of the zero polynomial is undefined.

How many terms are there in (p(x)=7x-2-1)?
B. (2)
\(7x^2\) और (-1) दो पद हैं। इसलिए यह द्विपदी भी है। / There are two terms \(7x^2\) and (-1). So it is also a binomial.

Which expression is written in standard polynomial form?
B. \(x^3+2x+5\)
मानक रूप में पद बड़ी घात से छोटी घात की ओर लिखे जाते हैं। \(x^3+2x+5\) इसी क्रम में है। / In standard form, terms are written from higher power to lower power. The expression \(x^3+2x+5\) follows this order.

If (p(x)=2x-2+3x-2), what is the value of (p(-2))?
A. (0)
(p(-2)=2(-2)2+3(-2)-2=0)। परीक्षा में ((-2)2) को (4) लिखना न भूलें। / (p(-2)=2(-2)2+3(-2)-2=0). In exams, remember that ((-2)2) is (4).

Which statement is correct for \(x^2+\sqrt{3}x+1\)?
A. यह बहुपद हैIt is a polynomial
\(\sqrt{3}\) वास्तविक गुणांक है और (x) की घातें पूर्ण संख्याएँ हैं। इसलिए यह बहुपद है। / \(\sqrt{3}\) is a real coefficient and the powers of (x) are whole numbers. Therefore it is a polynomial.
