Write $X = \left[\begin{array}{cc} 0 &1\cr -6 &-6 \end{array}\right]$ as a product $X = E_1 E_2 E_3$ of elementary matrices.

$E_1 =$ $\left[\Rule{0pt}{2.4em}{0pt}\right.$ $\left]\Rule{0pt}{2.4em}{0pt}\right.$ , $E_2 =$ $\left[\Rule{0pt}{2.4em}{0pt}\right.$ $\left]\Rule{0pt}{2.4em}{0pt}\right.$ , $E_3 =$ $\left[\Rule{0pt}{2.4em}{0pt}\right.$ $\left]\Rule{0pt}{2.4em}{0pt}\right.$ .
