The value of the determinant of the matrix [ 4 -9 -1 2] is?
The value of the determinant of the matrix [ 4 -9 -1 2] is?
Explanation
Given the matrix:
[4 -9]
[-1 2]
The determinant is calculated as:
(4 * 2) - (-9 * -1)
= 8 - 9
= -1
Given the matrix:
[4 -9]
[-1 2]
The determinant is calculated as:
(4 * 2) - (-9 * -1)
= 8 - 9
= -1
