Question

1. F A = [2 4 and B = [1 32
find 2A + B, A + 2B and A-B.​

Answer 1

Given,

A = [ 2  4]

B = [ 1  32]

1) 2A + B

= 2[2  4] + [1  32]

=  [4  8] + [ 1   32]

=  [ 4+1     32+8]

= [ 5     40]

2) A + 2B

= [2  4] + 2[1   32]

= [ 2   4] +  [2    64]

= [ 4     68]

3) A - B

= [2  4] - [ 1    32]

= [ 2-1    4-32]

= [1   -28]

Answer 2

Answer:

For - 2A+B

(2*A)+B

(2*24)+132

48+132

180

For- A+2B

A+(2*132)

24+264

288

For- A-B

24-132

-118
