2. Recall that in the Gauss-Jordan Method for row-reducing matrices, your friend will need to use row operations to turn column two into a unit column. Perform the following steps to turn column two into a unit column. (a) Start with the matrix below and perform R1 + -2 · R2 → R1. 1 2 1 1 1 1 -4 0 6 2 (b) Start with the matrix you ended with in part (a) and perform R3+ -6· R2 → R3.
