In order to solve a system, we want to \reduce" the augmented matrix to a form where we can easily identify the solution. This form is called \reduced-row echelon form." It is equivalent to the original system, but simpli ed. The method by which we simplify an augmented matrix to its reduced form is called the Gauss-Jordan Elimination Method.

Each successive row is the cyclic shift of the previous row: g i= g~ i 1, for i= 1;:::;k 1. As g(x)h(x) = xn 1, we have g 0h 0 = g(0)h(0) = 0n 1 6= 0 : In particular g 0 6= 0 (and h 0 6= 0).
