Equation (13.23) should be
[ x ˙ − x ˙ + 2 x − x 2 ] = [ 0 0 ] ⟺ [ x x ˙ ] = [ 0 0 ] , [ 2 0 ] . {\displaystyle \left[{\begin{array}{cc}{\dot {x}}\\-{\dot {x}}+2x-x^{2}\end{array}}\right]=\left[{\begin{array}{c}0\\0\end{array}}\right]\qquad \Longleftrightarrow \qquad \left[{\begin{array}{c}x\\{\dot {x}}\end{array}}\right]=\left[{\begin{array}{c}0\\0\end{array}}\right],\left[{\begin{array}{c}2\\0\end{array}}\right].}
