Hi there!

A matrix is said to be singular if it's determinant is zero.
So to find whether the matrix is singular or not we need to find the determinant.

Swarup1998: how did u write expanding... u should have mentioned that det(A) meaning the determinat of the matrix dear

Swarup1998: *determinant

Swarup1998: I meant that without writing the determinant... it is not appropriate to expand it... by the way.. good answer

Swarup1998: it is not always needed to write the expanding along which row or column... writing detA = some value, is also acceptable... no need of writing the determinant too
