It appears you've uploaded an image of a mathematical calculation. I'll analyze the content of the image to help you with it. Let's extract the mathematical expressions and details from the image.It seems I wasn't able to extract any text from the image. To assist you further, I'll need to manually interpret the content. Let me take a closer look at the mathematical expressions and calculations provided in the image.The image features a series of matrix operations, concluding with a matrix multiplication error marked by a red asterisk. It shows the process of multiplying two matrices, but with a mistake in the final multiplication step.

Here's a reconstruction of the steps:

1. Matrix multiplication is set up but not executed in the image. There appears to be an error in the dimensions or the entries of the matrices that prevent correct multiplication. The matrices involved are:
   - \( \begin{bmatrix} 3 & -2 \\ -4 & 1 \end{bmatrix} \)
   - \( \begin{bmatrix} 5 \\ -1 \end{bmatrix} \)

2. To multiply a \(2 \times 2\) matrix by a \(2 \times 1\) matrix, the resulting matrix should be \(2 \times 1\). The calculation should look like this:
   - First row: \( (3 \times 5) + (-2 \times -1) = 15 + 2 = 17 \)
   - Second row: \( (-4 \times 5) + (1 \times -1) = -20 - 1 = -21 \)

So, the correct product of the matrix multiplication should be:
\[
\begin{bmatrix} 17 \\ -21 \end{bmatrix}
\]

Would you like me to help with anything specific about this calculation or any other part of the image?

Here are five follow-up questions related to matrix operations:
1. How do you determine if two matrices can be multiplied?
2. What is the significance of the order of matrices in multiplication?
3. Can you explain the properties of matrix multiplication?
4. How does matrix multiplication apply to real-world problems?
5. What are some common mistakes to avoid when multiplying matrices?

**Tip:** When multiplying matrices, always ensure that the number of columns in the first matrix equals the number of rows in the second matrix for the multiplication to be defined.
