What is the product?
[4 3 -1 -1] x [-3 1 -2 -2]

Option A

|-6 -2|

|1 1|

Step-by-step explanation:

This is a product of a matrix.

So for the first number on the first row, we have;

(4 × -3) - (3 × -2) = -12 + 6 = -6

For the second number on the first row, we have;

(4 × 1) - (3 × 2) = 4 - 6 = -2

For the first number on the second row, we have;

(-1 × -3) - (-1 ×-2) = 3 - 2 = 1

For the second number on the second row, we have;

(-1 × 1) - (-1 × 2) = -1 + 2 = 1

Thus, we now have;

|-6 -2|

|1 1|

It's B, as in [ -18 10 5 -3]

Step-by-step explanation: I don't exactly wanna explain the entire process of multiplying matrices, but I ran it through multiple matrix calculators so I know it's right

a. is correct
