![### Matrix Multiplication Problem
#### Task
Compute the following matrix product:
\[
\begin{bmatrix}
1 & -2 \\
4 & -1
\end{bmatrix}
\begin{bmatrix}
2 & 4 \\
2 & 1
\end{bmatrix}
\]
#### Steps for Matrix Multiplication
To find the resultant matrix, we use the formula for matrix multiplication:
\[ C_{ij} = \sum A_{ik} B_{kj} \]
Each element of the resultant matrix is calculated by taking the dot product of the corresponding row from the first matrix and the column from the second matrix.
#### Detailed Explanation of the Resultant Matrix
Below the equation is a blank 2x2 matrix where the resulting values from matrix multiplication should be placed.
The answer boxes for the resultant matrix are arranged as follows:
\[
\begin{bmatrix}
\_\_ & \_\_ \\
\_\_ & \_\_
\end{bmatrix}
\]
