Alright so apparently there is some pattern in finding these determinants:

for the 2x2, the determinant of

|1 1|

|x y| is y - x

for 3x3, the determinant of

|1 1 1 |

|x y z |

|x^2, y^2, z^2| xy^2 - yx^2 - xz^2 +zx^2 + yz^2 - zy^2

Apparently that can be factored (not sure how), and using the roots, there will be a pattern that you can observe for finding a determinant of a 4x4, 5x5, etc of the same form (1, x, x^2, x^3, etc.)

How do you factor the 3x3 determinant, and what is the pattern?

Thanks!
