The determinant of this matrix can be calculated by multiplying
2
00:00:05.500 --> 00:00:11.859 A:middle L:90%
the diagonals of the values in this array. And
3
00:00:11.859 --> 00:00:26.149 A:middle L:90%
we can see that negative four times three minus negative
4
00:00:26.149 --> 00:00:31.489 A:middle L:90%
, five times. Two. Once we find these
5
00:00:31.489 --> 00:00:33.609 A:middle L:90%
products, we want to subtract them to find the
6
00:00:33.609 --> 00:00:36.289 A:middle L:90%
value of the determinant. So here we have a
7
00:00:36.289 --> 00:00:42.280 A:middle L:90%
product of negative 12 minus negative 10. And when
8
00:00:42.280 --> 00:00:46.219 A:middle L:90%
we simplify this statement, we get negative 12 plus
9
00:00:46.219 --> 00:00:50.250 A:middle L:90%
10 which gives us a value of negative, too
10
--> A:middle L:90%
