Consider the matrix equation -4 \times B^{3}-3 \times B^{2}+2 B=2 I \text { with } B=\left(\begin{array}{cc} 0 & -1 \\ 1 & 0 \end{array}\right) Find the matrix x x=\left(\begin{array}{cc} 14

/ 25 & 1 / 25 \\ 1 / 25 & 7 / 25 \end{array}\right) x=\left(\begin{array}{cc} 14 / 2 y & 2 / 25 \\ -2 / 25 & 14 / 25 \end{array}\right) x=\left(\begin{array}{cc} 7 & 1 \\ -1 & 7 \end{array}\right) x=\left(\begin{array}{cc} -2 & -2 / 7 \\ 2 / 7 & -2 \end{array}\right) \left\langle=\left(\begin{array}{cc} 14 / 25 & 2 / 25 \\ 6 / 25 & 8 / 25 \end{array}\right)\right.
