Question 570183
For this square matrix, the determinant is equal to


2 det A - 5 det B + 0 det C - 4 det D


where A,B,C,D are the 3x3 matrices whose entries are neither in a row or column of the top entry (e.g. matrix A would contain -2 0 2/-1 1 6/0 3 -2). Additionally, you would have to find the determinant of 3x3 matrices, which reduces to a several 2x2 matrices.


Since this problem requires a lot of "bashing" (not the correct word usage, but math people use it all the time), you could use a calculator. Most graphing calculators can evaluate determinants of square matrices.
