Hi, let's start the solution.
00:02
In this question we have a given matrix a that is 1 -1 -1 -1 -a b -c -d, a -scale, b -scale c -square, a -q, b -c -c -c -cube, d -c -cube.
00:11
Here, order of a matrix a is 4 -cross 4.
00:14
And question says that find the determinant of a matrix a.
00:20
So now let's start.
00:22
We know that the determinant is first element as it is.
00:25
Now hide first row, first column.
00:28
Then we get 3 -cross -3 matrix.
00:29
That is, b, c, d and this one is b square, c square, d square, p cube, c cube, d cube, minus a...
