Step 1 :Given the following matrices, if possible, determine $B A$. Identify the dimensions of the resulting matrix and fill out the matrix, if it exists. If not, state 'Not Possible'.
Step 2 :\[A=\left[\begin{array}{cc} 8 & -8 \\ -4 & 7 \end{array}\right] \quad B=\left[\begin{array}{c} -7 \\ 8 \\ 2 \end{array}\right]\]
Step 3 :The multiplication of two matrices is possible only when the number of columns in the first matrix is equal to the number of rows in the second matrix.
Step 4 :In this case, matrix A is a 2x2 matrix and matrix B is a 3x1 matrix.
Step 5 :The number of columns in matrix A (2) is not equal to the number of rows in matrix B (3).
Step 6 :Therefore, the multiplication BA is not possible.
Step 7 :\(\boxed{\text{Final Answer: Not Possible}}\)
