The matrices $P$ and $Q$ provided in the image are:

$P = \begin{bmatrix} 1 & 2 \\ 3 & 4 \\ 5 & -2 \end{bmatrix}$ $Q = \begin{bmatrix} -1 & 2 & 3 \\ -6 & 1 & -4 \end{bmatrix}$

Would you like me to perform a specific operation involving these matrices? For example, calculating the product $PQ$, the transpose of each matrix, or any other operation? Please specify your requirement.

If you have any questions or need further explanations on a related topic, feel free to ask!
