Find the determinant of

4...3...-5

5...2...-3

0..-1....2

3. The attempt at a solution

I've tried to get the answer using each of the 3 rows and each time I get a different answer. For the first row I get 14, the second row I get -31, and the third row I get -1. However, I thought that the determinant would be the same value for whichever row (or column) you choose to expand.
