Subtract the Matrices [[1,-1],[2,-1]]-[[2,-1],[-1,8]]

Problem

[[1,−1],[2,−1]]−[[2,−1],[−1,8]]

Solution

1. Identify the corresponding elements in each matrix that need to be subtracted.

2. Subtract the elements in the first row: 1 - 2a*n*d1 - (-1)$.

3. Subtract the elements in the second row: 2 - (-1)a*n*d1 - 8$.

4. Simplify the arithmetic results to form the resulting matrix.

Final Answer

[[1,−1],[2,−1]]−[[2,−1],[−1,8]]=[[−1,0],[3,−9]]
