For the following matrix,
[1, -3, 1]
[-4.-1,-2]
[0, -2,-2]
Perform the row operation: 4R1+R2→R2 (there are 9 boxes)
thank you,
I don't get it at all
Perform the row operation: 4R1+R2→R2
4R1 = 4[1,-3,1] = [4,-12,4]
4R1+R2 = [4,-12,4]+[-4,-1,-2] = [0,-13,2]
Replace R2 by the results
Enter the 9 matrix values (only row 2 has changed)
