1. The question asks how matrix $M$ was obtained. 2. To explain this, we need to know the context or the operation that produced matrix $M$ (e.g., multiplication, transformation, or definition). 3. Generally, a matrix $M$ can be obtained by: - Defining it explicitly by its elements. - Multiplying two or more matrices. - Applying a linear transformation to a basis. - Extracting it from a system of equations or data. 4. Without additional information about $M$, the exact method cannot be determined. 5. Please provide the original matrices or the operation used to get $M$ for a detailed explanation.
