Answer:
a = 1 , b = 0 and c = 5
Step-by-step 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
