Describe all solutions of Ax = 0 in vector parametric form, where A is row equivalent to the matrix given below:

(see attached image)

On this educational page, we will explore the following matrix, which is commonly used in linear algebra and related fields such as computer science, physics, and engineering.

The matrix is as follows:

\[
\begin{bmatrix}
1 & 2 & 0 & 0 & 1 & -1 \\
0 & 0 & 2 & 0 & -1 & 1 \\
0 & 0 & 0 & 1 & 1 & -1 \\
\end{bmatrix}
\]

**Explanation:**

This is a \( 3 \times 6 \) matrix, denoted as having 3 rows and 6 columns.

**Row 1:** 
\[ \begin{bmatrix}
1 & 2 & 0 & 0 & 1 & -1 
\end{bmatrix} \]

**Row 2:** 
\[ \begin{bmatrix}
0 & 0 & 2 & 0 & -1 & 1
\end{bmatrix} \]

**Row 3:** 
\[ \begin{bmatrix}
0 & 0 & 0 & 1 & 1 & -1
\end{bmatrix} \]

### Key Points:
- The elements of each row and column can represent different quantities, depending on the context, such as coefficients in a system of equations, or transformations in vector space.
- In this particular matrix:
  - The first row contains the elements: \(1, 2, 0, 0, 1, -1\)
  - The second row contains the elements: \(0, 0, 2, 0, -1, 1\)
  - The third row contains the elements: \(0, 0, 0, 1, 1, -1\)

### Applications:

- **Systems of Equations:** This matrix might be used to represent a system of linear equations where each row represents an equation and each column represents a variable.
- **Transformation Matrices:** It could also represent a transformation in a higher-dimensional vector space, where matrix multiplication alters the components of a vector according to the transformation rules.

### Conclusion:

Understanding how to read and work with matrices like this one is critical in various scientific and engineering disciplines. This basic knowledge is a stepping stone to more complex concepts and applications.
