Can someone please help me figure out how this matrix reduces? The matrix is:
I don't know how it becomes this matrix:
I understand how they get the 2 zeros in rows 3 and 4 and columns 1 and 2, but I do not understand how they got the 15 and 45 or how they managed to get the 2 zeros on row 1.
Thank you!
Code:
[ 1 -1/2 1 1 3 ]
[ 0 1 -2 0 0 ]
[ 0 13/2 -13 -6 -18 ]
[ 0 7/2 -7 -6 -18 ]
Code:
[ 1 0 0 1 3 ]
[ 0 1 -2 0 0 ]
[ 0 0 0 -6 -18 ]
[ 0 0 0 15 45 ]
Thank you!
