Solve the matrix, then find 2B – A².

If A = and B =
Find 2B – A²

Solution:

If A = and B = , C = , compute
(i) A(B + C)
(ii) (B + C)A

Solution:

More Solutions:

• Find the matrix C such that AC = B.
• Find matrix B such that BA = I, ,where I is unity matrix of order 2
• If A = [aij]2×2 where aij = i + j, then A is equal to.
• Then the values of x and y are x = 2, y = 3
• Then the value of x – y is (- 3).
• Then the matrix A is equal to.
