| 金声玉亮2.0 | To find the sum of the given polynomials f(x) = 4x - 5 and g(x) = 2x^2 - 4x + 2 in the polynomial ring Z_8[x], we need to add the coefficients of the corresponding terms. First, we need to rewrite the polynomials in the standard form, which is: f(x) = 4x - 5 = 4x - 5 + 0x^2 g(x) = 2x^2 - 4x + 2 Now, we can add the coefficients of the corresponding terms: (4x - 5 + 0x^2) + (2x^2 - 4x + 2) = ? We add the coefficients of the x^2 terms: 0 + 2 = 2 We add the coefficients of the x terms: 4 - 4 = 0 We add the constant terms: -5 + 2 = -3 So, the sum of the polynomials is: 2x^2 + 0x - 3 Since we are working in Z_8[x], we need to reduce the coefficients modulo 8. The coefficient of the constant term is -3, which is equivalent to 5 modulo 8. Therefore, the sum of the polynomials is: 2x^2 + 5 The correct answer is: A. 2x^2 + 5 |

| minimax | To find the sum of the given polynomials in the polynomial ring $\mathbb{Z}_8[x]$, we simply add the coefficients of the corresponding powers of $x$ together, taking into account that we are working in modulo 8 arithmetic. Given: $f(x) = 4x - 5$ $g(x) = 2x^2 - 4x + 2$ Adding $f(x)$ and $g(x)$ together: $(4x - 5) + (2x^2 - 4x + 2)$ Combine like terms: $= 2x^2 + (4x - 4x) + (-5 + 2)$ $= 2x^2 + 0x - 3$ Now, we need to reduce the constant term modulo 8: $-3 \equiv 5 \pmod{8}$ (since $-3 + 8 = 5$) So the sum of the polynomials is: $2x^2 + 5$ The correct answer is: A. $2x^2 + 5$ |

| wenxinyiyan | A Explanation: In the polynomial ring Z_8[x], we perform polynomial addition as usual, but the coefficients are reduced modulo 8. So, to find the sum of f(x) and g(x), we add the corresponding coefficients and reduce the results modulo 8. f(x) = 4x - 5 g(x) = 2x^2 - 4x + 2 Adding the corresponding terms, we get: 4x - 5 + 2x^2 - 4x + 2 = 2x^2 + (4x - 4x) + (-5 + 2) = 2x^2 + 0x - 3 Reducing the coefficients modulo 8, we get: 2x^2 + 0x + 5 (since -3 ≡ 5 (mod 8)) = 2x^2 + 5 Hence, the sum of the given polynomials in Z_8[x] is 2x^2 + 5. |

| zhipu | To find the sum of the polynomials \( f(x) = 4x - 5 \) and \( g(x) = 2x^2 - 4x + 2 \) in the polynomial ring \( \mathbb{Z}_8[x] \), we add the corresponding coefficients, considering the arithmetic modulo 8. Let's add \( f(x) \) and \( g(x) \) term by term: 1. The \( x^2 \) term: - \( g(x) \) has \( 2x^2 \). - \( f(x) \) has no \( x^2 \) term, so it contributes 0. - Thus, the \( x^2 \) term in the sum is \( 2x^2 \). 2. The \( x \) term: - \( f(x) \) has \( 4x \). - \( g(x) \) has \( -4x \). - Adding these, \( 4x + (-4x) = 0 \). 3. The constant term: - \( f(x) \) has \( -5 \). - \( g(x) \) has \( 2 \). - Adding these, \( -5 + 2 = -3 \). - In \( \mathbb{Z}_8 \), \( -3 \) is equivalent to \( 5 \) (since \( -3 + 8 = 5 \)). Putting these together, the sum of the polynomials is: \[ 2x^2 + 0x + 5 = 2x^2 + 5 \] So the correct answer is: A. \( 2x^2 + 5 \) |

| deepseekv3 | To find the sum of the polynomials \( f(x) = 4x - 5 \) and \( g(x) = 2x^2 - 4x + 2 \) in the polynomial ring \( \mathbb{Z}_8[x] \), follow these steps: 1. **Add the polynomials term by term:** \[ f(x) + g(x) = (4x - 5) + (2x^2 - 4x + 2) \] Combine like terms: \[ f(x) + g(x) = 2x^2 + (4x - 4x) + (-5 + 2) \] Simplify: \[ f(x) + g(x) = 2x^2 + 0x - 3 \] So: \[ f(x) + g(x) = 2x^2 - 3 \] 2. **Reduce the coefficients modulo 8:** The coefficient of \( x^2 \) is 2, and the constant term is \(-3\). Since we are working in \( \mathbb{Z}_8 \), we reduce \(-3\) modulo 8: \[ -3 \equiv 5 \pmod{8} \] Thus: \[ f(x) + g(x) = 2x^2 + 5 \] 3. **Match the result with the given options:** The result \( 2x^2 + 5 \) corresponds to option **A**. **Answer:** A |
