![**Simplify the following matrix expression:**
\[
\begin{bmatrix}
1 & 0 & -3 \\
4 & 5 & -2 \\
\end{bmatrix}
\begin{bmatrix}
1 & -4 & 0 & 2 \\
0 & -2 & -1 & 3 \\
1 & -1 & -3 & 5 \\
\end{bmatrix}
\]
**Explanation:**
The task is to perform matrix multiplication between a 2x3 and a 3x4 matrix. The result will be a 2x4 matrix. The elements of this resulting matrix are calculated by taking the dot product of the rows of the first matrix with the columns of the second matrix.
**Steps to Simplify:**
- Multiply elements across each row of the first matrix by the corresponding elements down each column of the second matrix, then sum the products.
- Continue this process to fill in all entries of the resulting 2x4 matrix.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd6a59ea6-6b49-4641-82f8-067b1c5942b1%2F27f58c99-6879-4e92-b69f-88f7c15b237c%2F0xfndr5_processed.jpeg&w=3840&q=75)
