Expert Solution
Concept used

Reduced row echelon form has four requirements:

  • The first non-zero number in the first row (the leading entry) is the number 1.
  • The second row also starts with the number 1, which is further to the right than the leading entry in the first row. For every subsequent row, the number 1 must be further to the right.
  • The leading entry in each row must be the only non-zero number in its column.
  • Any non-zero rows are placed at the bottom of the matrix.
