???????

Find the inverse of the following matrices, where possible, using the method shown in Week 9 only. Then verify your results (if you find that a matrix has no inverse, then verify by finding the determinant. If you find that it has an inverse, verify by multiplying with the original matrix and see if you get the identity matrix). (a) \( A=\left[\begin{array}{cc}-4 & -3 \\ 2 & 2\end{array}\right] \) (b) \( B=\left[\begin{array}{ccc}1 & 0 & -2 \\ 2 & 1 & -4 \\ -3 & 3 & 6\end{array}\right] \)
