Find Reduced Row Echelon Form [[1,2]]

Problem

[[1,2]]

Solution

1. Identify the leading entry of the first row. The first non-zero entry in the row is 1 which is located in the first column.

2. Check the conditions for Reduced Row Echelon Form (RREF). A matrix is in RREF if the first non-zero entry in every row is 1 and it is the only non-zero entry in its column.

3. Verify the column condition. In this matrix, the leading 1 is in the first column, and there are no other rows, so there are no other entries in that column to eliminate.

4. Conclude that the matrix already satisfies all requirements for RREF.

Final Answer

rref*[[1,2]]=[[1,2]]
