Overview
Reduced Row Echelon Form (RREF) is a powerful tool in linear algebra that simplifies matrices to make solving systems of equations straightforward. By transforming a matrix into RREF, we can easily identify whether a system has a unique solution, infinite solutions, or no solution at all. The proces...
Key Terms
Example: A 2x3 matrix has 2 rows and 3 columns.
Example: Swapping two rows is a row operation.
Example: In the row [0, 0, 1, 2], the leading entry is 1.
Example: In RREF, each leading 1 is in a pivot position.
Example: The equations x + y = 2 and x - y = 0 have a unique solution.
Example: The equations x + y = 2 and 2x + 2y = 4 have infinite solutions.
