Your textbook must have some examples of calculating determinant of a matrix.

If that does not help, try https://www.purplemath.com/modules/determs.htm

Then visit https://www.khanacademy.org/math/al...ding-the-determinant-of-a-3x3-matrix-method-2

Then visit https://www.khanacademy.org/math/li...-of-matrices/v/linear-algebra-nxn-determinant

Please show us what you have tried and exactly where you are stuck.
