Should I verify if the matrix is invertible before trying to find its inverse?
No, that is not necessary. If you enter a non-invertible matrix, Algebrator will
inform you and will ask you if you wish to find its determinant (so that you can
see that it is equal to zero, which is the indicator that the matrix is not
invertible).
