Answer: A reduced row echelon form (RREF) is a way of transforming a matrix into a simplified form that makes it easier to perform operations such as solving systems of linear equations. A matrix is in reduced row echelon form when it satisfies the following properties:
The first non-zero element in each row, called a pivot, is 1.
Each pivot is the only non-zero element in its column.
The rows above a pivot are zero except for the pivot.
The rows below a pivot are zero.
The columns to the right of a pivot contain only zeros.
An RREF matrix can be used to identify the solutions to a system of linear equations, or to determine if the system has no solutions or infinitely many solutions.
