Calculate $$$\left[\begin{array}{ccc}3 & 2 & 2\\2 & 3 & -2\end{array}\right]\cdot \left[\begin{array}{cc}3 & 2\\2 & 3\\2 & -2\end{array}\right].$$$

Solution

$$$\left[\begin{array}{ccc}{\color{GoldenRod}3} & {\color{Fuchsia}2} & {\color{Red}2}\\{\color{Violet}2} & {\color{SaddleBrown}3} & {\color{Chartreuse}-2}\end{array}\right]\cdot \left[\begin{array}{cc}{\color{Fuchsia}3} & {\color{OrangeRed}2}\\{\color{BlueViolet}2} & {\color{DarkBlue}3}\\{\color{Violet}2} & {\color{Peru}-2}\end{array}\right] = \left[\begin{array}{cc}{\color{GoldenRod}\left(3\right)}\cdot {\color{Fuchsia}\left(3\right)} + {\color{Fuchsia}\left(2\right)}\cdot {\color{BlueViolet}\left(2\right)} + {\color{Red}\left(2\right)}\cdot {\color{Violet}\left(2\right)} & {\color{GoldenRod}\left(3\right)}\cdot {\color{OrangeRed}\left(2\right)} + {\color{Fuchsia}\left(2\right)}\cdot {\color{DarkBlue}\left(3\right)} + {\color{Red}\left(2\right)}\cdot {\color{Peru}\left(-2\right)}\\{\color{Violet}\left(2\right)}\cdot {\color{Fuchsia}\left(3\right)} + {\color{SaddleBrown}\left(3\right)}\cdot {\color{BlueViolet}\left(2\right)} + {\color{Chartreuse}\left(-2\right)}\cdot {\color{Violet}\left(2\right)} & {\color{Violet}\left(2\right)}\cdot {\color{OrangeRed}\left(2\right)} + {\color{SaddleBrown}\left(3\right)}\cdot {\color{DarkBlue}\left(3\right)} + {\color{Chartreuse}\left(-2\right)}\cdot {\color{Peru}\left(-2\right)}\end{array}\right] = \left[\begin{array}{cc}17 & 8\\8 & 17\end{array}\right]$$$

Answer

$$$\left[\begin{array}{ccc}3 & 2 & 2\\2 & 3 & -2\end{array}\right]\cdot \left[\begin{array}{cc}3 & 2\\2 & 3\\2 & -2\end{array}\right] = \left[\begin{array}{cc}17 & 8\\8 & 17\end{array}\right]$$$A
