Show that 6X – X² = 9I Where I is the unit matrix.

If X = , show that 6X – X² = 9I Where I is the unit matrix.

Solution:

Show that is a solution of the matrix equation X² – 2X – 3I = 0,Where I is the unit matrix of order 2

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.
