Use elementary row or column operations to find the determinant.
Using Elementary Row Operations to Determine A−1. A linear system is said to be square if the number of equations matches the number of unknowns. If the system A x = b is square, then the coefficient matrix, A, is square. If A has an inverse, then the solution to the system A x = b can be found by multiplying both sides by A −1: Expert Answer. Determinant of matrix given in the question is 0 as the determinant of the of the row e ….

Question: Use either elementary row or column operations, or cofactor expansion, to find the determinant by hand. Then use a software program or a graphing utility to verify your answer. ∣∣1−176301143 ...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. See Answer.

To compute |kA|, you need to know that everytime you scale a row of a matrix, it scales the determinant. There are 3 rows in A, so kA is A with 3 rows scaled by k, which multiplies the determinant of A by k^3. In general if A is n x n, then |kA|=k^n |A|.
