If A=(123−1)A = \begin{pmatrix} 1 & 2 \\ 3 & -1 \end{pmatrix}A=(132−1), what is A2A^2A2 (that is, A⋅AA \cdot AA⋅A)?
(1491)\begin{pmatrix} 1 & 4 \\ 9 & 1 \end{pmatrix}(1941)
(7007)\begin{pmatrix} 7 & 0 \\ 0 & 7 \end{pmatrix}(7007)
(7−337)\begin{pmatrix} 7 & -3 \\ 3 & 7 \end{pmatrix}(73−37)
(123−1)\begin{pmatrix} 1 & 2 \\ 3 & -1 \end{pmatrix}(132−1)
