You asked:

Evaluate the expression: \(\begin{bmatrix}9 & -3 & 0 \\ -3 & 15 & -12 \\ 0 & -12 & 16\end{bmatrix}\)

MathBot Answer:

You have entered a numeric matrix.

The determinant of the matrix is \(720\).

The inverse of the matrix is: \[\left[\begin{matrix}\frac{2}{15} & \frac{1}{15} & \frac{1}{20}\\\frac{1}{15} & \frac{1}{5} & \frac{3}{20}\\\frac{1}{20} & \frac{3}{20} & \frac{7}{40}\end{matrix}\right]\]

The matrix has the following properties:

 The matrix is square.

 The matrix is symmetric.
