Use the augmented matrix method to find the inverse of matrix [math]A[/math].
[list=1] [*]Combine the matrix [math]A[/math] with the identity matrix, [math]I[/math], to create an augmented matrix. [*]Perform elementary row operations to change the left side of the augmented matrix into the identity matrix. [*]Write the inverse matrix.
