Answer:
a^2 - a + bc = [ 2 -2
3 -2]
Step-by-step explanation:
GIVEN:
a = [ 4 -2 , b = [ 0 2 , c = [ -2 3
6 -3] 1 -1] 1 -1]
a^2 = [ 4 -2 x [ 4 -2
6 -3] 6 -3]
a^2 = [ 4 -2
6 -3]
bc = [ 0 2 x [ -2 3
1 -1] 1 -1]
bc = [2 2
-3 2]
a^2 - a + bc = [ 4 -2 - [ 4 -2 + [2 2
6 -3] 6 -3] -3 2 ]
= [ 4 -2 - [ 6 0
6 -3] 3 -1]
= [ -2 -2
