WebStep 1 Determine the left-most column containing a non-zero entry (it exists if the matrix is non-zero). Step 2 If needed, perform a type I operation so that the first non-zero column has a non-zero entry in the first row. Step 3 If needed, perform a type II operation to make that first non-zero entry 1 (the leading 1 in the first row). Step 4 WebTo get rref you usually have to divide one or more rows by a pivot coefficient, which changes the value of the determinant (to "one" if the matrix is invertible). When you just do a row operation like he did here, you're not dividing a row by a number, and so as you see in the video that doesn't change the value of the determinant. Comment
