Which matrix will always give a determinant of 0?

The use of determinants simplifies in a very remarkable way the resolution of systems of linear equations. To this end, general properties are applied that allow for the discussion and resolution of such systems through a rigorous procedure.

In the management of determinants, some properties can be established that facilitate calculation operations. Among those properties we have:

>> The determinant of a matrix with two rows or two equal columns is null.

Answer:

a matrix having two equal rows
