金声玉亮2.0	To find the zeros of the polynomial $x^2 + 1$ in the finite field $\mathbb{Z}_2$, we need to find the values of $x$ in $\mathbb{Z}_2$ that make the polynomial equal to zero. In $\mathbb{Z}_2$, the only possible values for $x$ are $0$ and $1$. Let's evaluate the polynomial for each of these values: 1. For $x = 0$: \[x^2 + 1 = 0^2 + 1 = 1\] Since $1$ is not equal to zero in $\mathbb{Z}_2$, $x = 0$ is not a zero of the polynomial. 2. For $x = 1$: \[x^2 + 1 = 1^2 + 1 = 2\] In $\mathbb{Z}_2$, $2$ is equivalent to $0$ because $2 \mod 2 = 0$. Therefore, $x = 1$ is a zero of the polynomial. So, the only zero of the polynomial $x^2 + 1$ in $\mathbb{Z}_2$ is $1$. The correct answer is B.	B
deepseekr1	The polynomial \( x^2 + 1 \) in \( \mathbb{Z}_2 \) is evaluated by substituting each element of the field (0 and 1) into the polynomial: - For \( x = 0 \): \( 0^2 + 1 = 0 + 1 = 1 \neq 0 \), so 0 is not a root. - For \( x = 1 \): \( 1^2 + 1 = 1 + 1 = 2 \equiv 0 \mod 2 \), so 1 is a root. The polynomial factors as \( (x + 1)^2 \) in \( \mathbb{Z}_2[x] \), confirming that 1 is the only root (with multiplicity 2). However, in the field \( \mathbb{Z}_2 \), roots are counted without multiplicity, so the only zero is 1. Answer: B	B

To find the zeros of the polynomial $x^2 + 1$ in the finite field $\mathbb{Z}_2$, we need to find the values of $x$ in $\mathbb{Z}_2$ that make the polynomial equal to zero.

In $\mathbb{Z}_2$, the only possible values for $x$ are $0$ and $1$. Let's evaluate the polynomial for each of these values:

1. For $x = 0$:
\[x^2 + 1 = 0^2 + 1 = 1\]
Since $1$ is not equal to zero in $\mathbb{Z}_2$, $x = 0$ is not a zero of the polynomial.

2. For $x = 1$:
\[x^2 + 1 = 1^2 + 1 = 2\]
In $\mathbb{Z}_2$, $2$ is equivalent to $0$ because $2 \mod 2 = 0$. Therefore, $x = 1$ is a zero of the polynomial.

So, the only zero of the polynomial $x^2 + 1$ in $\mathbb{Z}_2$ is $1$.

The correct answer is B.

deepseekr1

The polynomial $ x^2 + 1 $ in $ \mathbb{Z}_2 $ is evaluated by substituting each element of the field (0 and 1) into the polynomial:

- For $ x = 0 $: $ 0^2 + 1 = 0 + 1 = 1 \neq 0 $, so 0 is **not** a root.
- For $ x = 1 $: $ 1^2 + 1 = 1 + 1 = 2 \equiv 0 \mod 2 $, so 1 **is** a root.

The polynomial factors as $ (x + 1)^2 $ in $ \mathbb{Z}_2[x] $, confirming that 1 is the only root (with multiplicity 2). However, in the field $ \mathbb{Z}_2 $, roots are counted without multiplicity, so the only zero is **1**.

The polynomial given is $ x^2 + 1 $ in the finite field $ \mathbb{Z}_2 $.

In $ \mathbb{Z}_2 $, the elements are 0 and 1.

Let's check if 0 is a zero of the polynomial:
\[ 0^2 + 1 = 0 + 1 = 1 \]
So, 0 is not a zero of the polynomial.

Now, let's check if 1 is a zero of the polynomial:
\[ 1^2 + 1 = 1 + 1 = 2 \equiv 0 \mod 2 \]
So, 1 is a zero of the polynomial.

Therefore, the answer is:

In Z_2 (the field with elements 0 and 1), let's substitute 0 and 1 for x in the polynomial x^2 + 1. When x = 0, 0^2 + 1 = 1. When x = 1, 1^2 + 1 = 2 which is 0 in Z_2. So the zero is 1. The answer is B.

C. 0,1

In the finite field Z_2, the elements are {0, 1}. To find the zeros of the polynomial x^2 + 1, we need to find the values of x for which the polynomial equals zero.

Setting the polynomial equal to zero gives us:

x^2 + 1 = 0

In Z_2, the addition and multiplication are modulo 2, so we have:

x^2 = -1

Since -1 is equivalent to 1 in Z_2 (because 1 + 1 = 2 ≡ 0 (mod 2)), we can rewrite the equation as:

x^2 = 1

The solutions to this equation in Z_2 are x = 0 and x = 1, because:

0^2 = 0 ≡ 0 (mod 2)
1^2 = 1 ≡ 1 (mod 2)

Therefore, the zeros of the polynomial x^2 + 1 in Z_2 are 0 and 1.

To find the zeros of the polynomial $x^2 + 1$ in the finite field $\mathbb{Z}_2$, we need to consider all possible values of $x$ in $\mathbb{Z}_2$ and check if they satisfy the equation.

The finite field $\mathbb{Z}_2$ has two elements: 0 and 1.

Let's check each one:

1. For $x = 0$:
\[0^2 + 1 = 0 + 1 = 1 \neq 0\]
So, $x = 0$ is not a zero of the polynomial.

2. For $x = 1$:
\[1^2 + 1 = 1 + 1 = 0 \text{ (in } \mathbb{Z}_2\text{)}\]
So, $x = 1$ is a zero of the polynomial.

Since $x = 0$ is not a zero and $x = 1$ is a zero, the correct answer is:

Explanation:
In the finite field Z_2 (also known as GF(2) or F_2), there are only two elements: 0 and 1.

To find the zeros of the polynomial x^2 + 1 in Z_2, we need to check both elements of the field:

1. When x = 0:
x^2 + 1 = 0^2 + 1 = 1 ≠ 0 (in Z_2)
So, x = 0 is not a zero of the polynomial.
2. When x = 1:
x^2 + 1 = 1^2 + 1 = 2 ≡ 0 (mod 2)
Since we are working in Z_2, 2 is equivalent to 0 modulo 2. Therefore, x = 1 is a zero of the polynomial.

Hence, the only zero of x^2 + 1 in Z_2 is 1.

1. For $ x = 0 $:
\[
0^2 + 1 = 0 + 1 = 1 \neq 0

So, $ x = 0 $ is not a zero of the polynomial.

2. For $ x = 1 $:
\[
1^2 + 1 = 1 + 1 = 2 \equiv 0 \pmod{2}
\]
So, $ x = 1 $ is a zero of the polynomial.

To find all zeros of the polynomial $ x^2 + 1 $ in the finite field $ \mathbb{Z}_2 $, we evaluate the polynomial at each element of $ \mathbb{Z}_2 $.

The elements of $ \mathbb{Z}_2 $ are $ 0 $ and $ 1 $.

1. **Evaluate at $ x = 0 $:**
\[
0^2 + 1 = 0 + 1 = 1 \neq 0
\]
So, $ 0 $ is not a zero.

2. **Evaluate at $ x = 1 $:**
\[
1^2 + 1 = 1 + 1 = 2 \equiv 0 \ (\text{mod} \ 2)
\]
So, $ 1 $ is a zero.

Therefore, the only zero of $ x^2 + 1 $ in $ \mathbb{Z}_2 $ is $ 1 $.
