Multiply the following matrices 2 1 3 0 2 1 1 1 4 3 1 2 1 0

Multiply the following matrices: [2 1 3 0 -2 1 1 -1 4] [-3 1 2 -1 0 3 0 2 1] = Answer Choices: Matrix A Matrix B Matrix C Select one: Matrix A Matrix B Matrix C

Solution

Matrix A

Matrix B

c11 = 2 x (-3) + 0 x 1 + 1 x 2 = -4

c12 = 2 x (-1) + 0 x 0 + 1 x 3 = 1

c13 = 2 x 0 + 0 x 2 + 1 x 1 = 1

c21 = 1 x (-3) + (-2) x 1 + (-1) x 2 = -7

c22 = 1 x (-1) + (-2) x 0 + (-1) x 3 = -4

c23 = 1 x 0 + (-2) x 2 + (-1) x 1 = -5

c31 = 3 x (-3) + 1 x 1 + 4 x 2 = 0

c32 = 3 x (-1) + 1 x 0 + 4 x 3 = 9

c33 = 3 x 0 + 1 x 2 + 4 x 1 = 6

Result:

matrix A

	A1	A2	A3
1	2	0	1
2	1	-2	-1
3	3	1	4
