Let $X = \left[\begin{array}{cc} -6 &1\cr -6 &5 \end{array}\right]$. Give an example of two $2 \times 2$ matrices $A$ and $B$, neither of which is the identy matrix $I$, such that $AB = X$.

$A =$ $\left[\Rule{0pt}{2.4em}{0pt}\right.$$\left]\Rule{0pt}{2.4em}{0pt}\right.$, $B =$ $\left[\Rule{0pt}{2.4em}{0pt}\right.$$\left]\Rule{0pt}{2.4em}{0pt}\right.$
