**Matrix Multiplication Using Partitioning Matrices Method**

**Problem Statement:**
For the given matrices \( A \) and \( B \), fill up the blank on \( C = AB \) by using the Partitioning Matrices method.

**Note:**
- Only use the required part of matrices \( A \) and \( B \) to compute the missing part of matrix \( C \).
- Do not use the entire matrices \( A \) and \( B \).

**Given Matrices:**

\[
A = \begin{pmatrix}
2 & 1 & 3 & 4 & -1 \\ 
1 & 2 & -1 & 1 & 4 \\ 
3 & 1 & 2 & 1 & 1 \\ 
-5 & -1 & 4 & 7 & 2 \\ 
-1 & 2 & 1 & -4 & 6
\end{pmatrix}
\]

\[
B = \begin{pmatrix}
1 & 2 & 3 & 4 \\ 
1 & 2 & 1 & 3 \\ 
2 & 1 & 2 & 5 \\ 
3 & 2 & 1 & 2 \\ 
4 & 2 & 6 & 1
\end{pmatrix}
\]

**Solution:**

Using the partitioning matrices method, we need to find the missing elements of matrix \( C \):

\[
C = A * B
\]

Given partial matrix \( C \):

\[
C = \begin{pmatrix}
48 & 40 & & \\ 
33 & 5 & & \\ 
24 & 26 & 42 & \\ 
28 & 38 & 54 & \\ 
33 & 34 & 42 & \\ 
33 & 74 & 79 & 54
\end{pmatrix}
\]

**Method:**
To find the missing parts of matrix \( C \), we need to multiply the relevant parts of matrices \( A \) and \( B \).

Calculate:

- For \( c_{1, 1} \), \( c_{1, 2} \)
  \[
  c_{1, 1} = 2*1 + 1*1 + 3*2 + 4*3 + (-1)*4 = 48
  \]
  \[
  c_{1, 2
