Find the product.-2 [7 - 4 0]

[ - 3 0 5 ]

[ 6 2 1]

It says find the product, so that means multiplication

-2[7 - 4 0] = [-14 8 0] solving: [-14 8 0] [-3 0 5]

[42+0+70 - 24+0+40 0+0+0]

[-14 8 0] * [-3 0 5] = [112 0 - 30] = [112 16 0]

[112 16 0]*[6 2 1]

[112 0 - 30] * [6 2 1] = [1008 114 0] [672+224+112 96+32+16 + 0]

=[1008 114 0].
