WebSo if I subtract the third row from the second row I'm just going to get a bunch of 0's. 0 minus 0 is 0. 1 minus 1 is 0. Minus 2 minus minus 2 is 0. And minus 1 minus minus 1. That's minus 1 plus 1. That's equal to 0. And just like that we have it now in reduced row echelon form. So this right here is the reduced row echelon form of A. WebThe row echelon form is a type of structure a matrix can have, that looks like triangular, but it is more general, and you can use the idea of row echelon form for non-square matrices. …
