When will ((u+2)x-4+(u+2)x+15) become a constant polynomial?
B. जब (u=-2)When (u=-2)
नियतांक बनने के लिए \(x^4\) और (x) दोनों के गुणांक (0) चाहिए। (u+2=0) से दोनों पद हट जाते हैं। / To become constant, the coefficients of both \(x^4\) and (x) must be (0). From (u+2=0), both terms disappear.

In \(6x^8-5x^6+3\), what are the coefficients of \(x^7\), \(x^5\), and (x)?
B. (0), (0), और (0)(0), (0), and (0)
इन घातों वाले पद बहुपद में नहीं हैं। इसलिए तीनों गुणांक (0) हैं। / The terms with these powers are not present in the polynomial. Therefore all three coefficients are (0).

If (r=3), what will be the degree of (\(r^2-9\)x-7+(r-1)x-4+x-2)?
B. (4)
(r=3) पर \(x^7\) का गुणांक (0) और \(x^4\) का गुणांक (2) होता है। इसलिए डिग्री (4) है। / For (r=3), the coefficient of \(x^7\) is (0) and the coefficient of \(x^4\) is (2). Therefore the degree is (4).

What is obtained by simplifying (x-3\(x^2-5\)-x-5+9x-3)?
B. \(4x^3\)
(x-3\(x^2-5\)=x-5-5x-3), फिर \(-x^5\) से \(x^5\) कटता है। सरल रूप \(4x^3\) है। / (x-3\(x^2-5\)=x-5-5x-3), then \(-x^5\) cancels \(x^5\). The simplified form is \(4x^3\).

What type of polynomial is the simplified form \(4x^3\)?
C. त्रिघात एकपदी बहुपदCubic monomial polynomial
\(4x^3\) में एक पद है और सबसे बड़ी घात (3) है। इसलिए यह त्रिघात एकपदी बहुपद है। / \(4x^3\) has one term and the highest power is (3). So it is a cubic monomial polynomial.

Which conclusion is correct for \(x^0+\sqrt{2}x^5-\frac{4x^2}{9}\)?
B. यह बहुपद है और डिग्री (5) हैIt is a polynomial and degree is (5)
\(\sqrt{2}\) और \(-\frac{4}{9}\) वास्तविक गुणांक हैं। (x) की घातें (0), (5), और (2) हैं। / \(\sqrt{2}\) and \(-\frac{4}{9}\) are real coefficients. The powers of (x) are (0), (5), and (2).

If (d=-1), what will be the degree of ((d+1)x-5+(2d+3)x-2+7)?
B. (2)
(d=-1) रखने पर \(x^5\) का गुणांक (0) और \(x^2\) का गुणांक (1) होता है। इसलिए सबसे बड़ी घात (2) है। / Putting (d=-1) makes the coefficient of \(x^5\) equal to (0) and the coefficient of \(x^2\) equal to (1). So the highest power is (2).

For which value will the degree of ((2a-8)x-6+(a+1)x-3+4) be (3)?
C. (a=4)
डिग्री (3) के लिए \(x^6\) का गुणांक (0) होना चाहिए और \(x^3\) का गुणांक अशून्य रहना चाहिए। (2a-8=0) से (a=4) मिलता है। / For degree (3), the coefficient of \(x^6\) must be (0) and the coefficient of \(x^3\) must remain non-zero. From (2a-8=0), (a=4).

Why is \(\frac{x^2-4}{x-2}\) not considered a polynomial in its original form?
C. क्योंकि चर हर में हैBecause the variable is in the denominator
मूल रूप में हर (x-2) है, इसलिए यह सीधे बहुपद नहीं कहलाता। सरल करने पर भी \(x\neq2\) की शर्त रहती है। / In the original form, the denominator is (x-2), so it is not directly called a polynomial. Even after simplifying, the condition \(x\neq2\) remains.
