Question

Jawb ya 24-26 pakai cara

Answer 1

24)
A=[1 1] dan B=[0 1]
[-1 1] [1 0], maka (A+B)(A-B)-(A-B)(A+B)
(A+B)= [1 1] + [0 1] = [1 2]
[-1 1] [1 0] [0 1]
(A-B)= [1 1] - [0 1] = [1 0]
[-1 1] [1 0] [-2 1]
maka (A+B)(A-B)-(A-B)(A+B)
[1 2] [1 0] - [1 0] [1 2]
[0 1].[-2 1] [-2 1].[0 1]
=[1-4 0+2] - [1+0 2+0]
[0-2 0+1] [-2+0 -4+1]
=[-3 2] - [1 2]
[-2 1] [-2 -3]
=[-4 0]
[0 4]
=4[-1 0]
[0 1]
