Answer 2

a = 1 , b = 0 and c = 5

Explanation:

The given matrix are,

[2 1 0] X 1 -1 2 = [a b c]

-1 -2 1

0 1 1

a = (2*1) + (1*-1) +(0*0) = 2 -1 + 0 = 1

b = (2*-1) + (1*-2) +(0*1) =-2 -2 + 0 = 0

c = (2*2) + (1*1) +(0*1) = 4 +1 + 0 = 5

Therefore the values of a,b, and c are

a= 1 , b = 0 and c = 5
