❖ Difference between Gauss Jordan elimination (RREF) Vs Gaussian elimination (REF).

RREF & REF

(*) To solve by Gauss-Jordan elimination, we have to put it in the Reduced Row Echelon Form (RREF) which we have explained before at the beginning of the videos in this playlist (Linear Algebra).

(**) To solve by Gaussian elimination, we have to put it in the Row Echelon Form (REF). Then, we have to solve it backward substitution which we will discuss in the next video!

So, Gauss Jordan Elimination & Gaussian Elimination are fundamental techniques in solving systems of linear equations.

❖ This is one of the first things you’ll learn in a Linear Algebra Course. Here’s what you need to know about the Gauss-Jordan elimination Vs Gaussian elimination.
