What is the degree of the polynomial (p(x)=11x-6-4x-3+x-9)?
C. (6)
सबसे बड़ी घात (6) है इसलिए घात (6) होगी। गुणांक नहीं बल्कि चर की सबसे ऊंची घात देखें। / The highest power is (6), so the degree is (6). Look at the highest power of the variable, not the coefficient.

What is the coefficient of \(x^2\) in (p(x)=5x-3-8x-2+13x-21)?
B. (-8)
\(x^2\) वाले पद \(-8x^2\) का गुणांक (-8) है। संकेत सहित गुणांक लिखना जरूरी है। / The coefficient of the \(x^2\)-term \(-8x^2\) is (-8). Write the coefficient with its sign.

Which is the constant term in the polynomial (p(t)=4t-5-6t-2+t+15)?
D. (15)
जिस पद में (t) नहीं है वह अचर पद है। यहां अचर पद (15) है। / The term without (t) is the constant term. Here the constant term is (15).

Which of the following is not a polynomial in (y)?
D. \(y^2+\frac{4}{y}\)
\(y^2+\frac{4}{y}\) में \(\frac{4}{y}=4y^{-1}\) है इसलिए घात ऋणात्मक है। ऋणात्मक घात वाला चर बहुपद नहीं बनाता। / In \(y^2+\frac{4}{y}\), \(\frac{4}{y}=4y^{-1}\), so the power is negative. A variable with a negative power is not a polynomial.

How many effective terms are there in the polynomial \(7x^4-3x^3+0x^2+5\)?
B. (3)
\(0x^2\) प्रभावी पद नहीं है इसलिए पद \(7x^4\), \(-3x^3\) और (5) हैं। शून्य गुणांक वाले पद को न गिनें। / The term \(0x^2\) is not effective, so the terms are \(7x^4\), \(-3x^3\), and (5). Do not count a term with zero coefficient.

If (p(x)=2x-2+3x-11), what is the value of (p(2))?
C. (3)
(p(2)=2(2)2+3(2)-11=3)। मान निकालते समय पहले घात का मान निकालें। / (p(2)=2(2)2+3(2)-11=3). While evaluating, calculate the power first.

For (q(x)=x-3+2x-2-5x-6), what is (q(-2))?
C. (4)
(q(-2)=-8+8+10-6=4)। ऋणात्मक मान रखते समय प्रत्येक पद का संकेत अलग जांचें। / (q(-2)=-8+8+10-6=4). Check the sign of every term separately when substituting a negative value.

What type of polynomial is \(12x^2-7x+4\)?
C. त्रिपदीTrinomial
इसमें (3) प्रभावी पद हैं इसलिए यह त्रिपदी है। पदों की संख्या से नाम पहचाना जाता है। / It has (3) effective terms, so it is a trinomial. The name is identified by the number of terms.

If (p(x)=(a+3)x-2+5x-1) is a linear polynomial, what is (a)?
A. (-3)
रैखिक होने के लिए \(x^2\) का गुणांक (0) होना चाहिए। इसलिए (a+3=0) और (a=-3)। / For it to be linear, the coefficient of \(x^2\) must be (0). Hence (a+3=0) and (a=-3).

What is the degree of the non-zero constant polynomial (p(x)=-18)?
A. (0)
अशून्य अचर बहुपद की घात (0) होती है। अचर संख्या का अर्थ घात (0) से जुड़ा है। / A non-zero constant polynomial has degree (0). A constant number is linked with degree (0).
