A_{x}^{2}\leq \left(\sqrt{10}\right)^{2}
Calculate the square root of 10 and get \sqrt{10}. Rewrite 10 as \left(\sqrt{10}\right)^{2}.
|A_{x}|\leq \sqrt{10}
Inequality holds for |A_{x}|\leq \sqrt{10}.
A_{x}\in \begin{bmatrix}-\sqrt{10},\sqrt{10}\end{bmatrix}
Rewrite |A_{x}|\leq \sqrt{10} as A_{x}\in \left[-\sqrt{10},\sqrt{10}\right].
