Step-by-step explanation:
Maybe you want the determinant of ...
![\left[\begin{array}{cc}5&9\\8&-2\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D5%269%5C%5C8%26-2%5Cend%7Barray%7D%5Cright%5D)
The determinant of a 2×2 matrix is the difference of the products of elements on the down diagonal and the up diagonal:
D = (5)(-2) -(8)(9) = -10 -72 = -82
The determinant of this matrix is -82.
