Question

In a second order determinant
Rows & Columns are​

Answer 1

Answer:

Second-Order Determinant: For matrices of order 2, you calculate the determinant of the matrix by multiplying the diagonally opposite elements in the matrix, and finding the difference between these two products.

Answer 2

Answer:

In the determinant

each of the numbers 2, 5, 6, and 1 is called an element. There are two rows, the first row containing the elements 2 and 5, and the second row having the elements 6 and 1. There are also two columns, the first with elements 2 and 6, and the second with elements 5 and 1. The elements along the principal diagonal are 2 and 1, and along the secondary diagonal they are 5 and 6.
