How do you write the matrix #[(1, -3, 0, -7), (-3, 10, 1, 23), (4, -10, 2, -24)]# using the row echelon form?
The matrix is
This is the matrix in reduced row echelon form.
Row echelon form has the form
The available operations include
- Swap rows (
- Multiply/divide a row by a constant
- Add/subtract rows
Multiply Row 1 by
Notice in this last step that that
Because no further manipulation will produce the final form,
We are finished.
