Here we explain how to find the determinant of a 3×3 matrix using the cofactor expansion method or using the shortcut method. Also, you will see examples of the computations of 3×3 determinants and, finally, you will find solved exercises so that you can practice and perfectly understand how to evaluate the determinant of a 3×3 matrix.
If the equations a 1 x + b 1 = 0, a 2 x + b 2 = 0 are satisfied by the same value of x, then a 1 b 2 – a 2 b 1 = 0. The expression a 1 b 2 – a 2 b 1 is called a determinant of the second order, and it is denoted by. A determinant of second order consists of two rows and two columns. Next consider the system of equations a 1 x + b 1 y + c 1 ...
