Question 206225: Hi all, I have a Matrix problem that I am not quite sure of how to solve.
For the given matrix A:
(1 2 3)
(2 1 -1)
(2 0 1)
a) Write the matix 4a. (Does this just mean I solve it by multiplying each number by 4?) and
b) Use matrix multiplication to find A^2 = AA.
Any help would be most appreciated.

You can put this solution on YOUR website! For the given matrix A:
(1 2 3)
(2 1 -1)
(2 0 1)
a) Write the matix 4a. (Does this just mean I solve it by multiplying each number by 4?)
That's it. 4 times each element.

and
b) Use matrix multiplication to find A^2 = AA.
