Determine which property of determinants the equation illustrates.The easiest thing to think about in my head from here, is that we know how elementary operations affect the determinant. Swapping rows negates the determinant, scaling rows scales it, and adding rows doesn't affect it. So for instance, we can multiply the bottom row of this matrix by $-x$ to get that $$ \frac{1}{-x}\begin{vmatrix} x^2 & x ...We can perform elementary column operations: if you multiply a matrix on the right by an elementary matrix, you perform an "elementary column operation". However, elementary row operations are more useful when dealing with things like systems of linear equations, or finding inverses of matricces. For large matrices, the determinant can be calculated using a method called expansion by minors. This involves expanding the determinant along one of the rows or columns and using the determinants of smaller matrices to find the determinant of the original matrix. 2.
