To find the difference between two matrices, subtract corresponding elements. For the given matrices:- For the first element: $(-1) - 2 = -3$- For the second element in the first row: $3 - 1 = 2$- For the first element in the second row: $0 - 7 = -7$- For the second element in the second row: $4 - 4 = 0$- For the first element in the third row: $7 - 4 = 3$- For the second element in the third row: $(-4) - 2 = -6$Thus, the resulting matrix is $\left[ \begin{array} { r r } - 3 & 2 \ - 7 & 0 \ 3 & - 6 \end{array} \right]$.
