(a) Determine E, a product of elementary matrices, which when premultiplying Aperforms a Gauss-Jordan pivot on the (3,3) entry of
A={1 0 -5 3
0 1 1 6
0 0 3 21)
To enter a matrix click on the 3x3 grid of squares below. Next select the exact size of the matrix you want.
Then change the entries in the matrix to the entries of your answer. If you need to start over then click on the trash can.
(b) Enter the product EA. It should be in reduced row echelon form.
