If is such that A2 = I, then

As A2 = I,So, α2 + βγ = 1α2 + βγ – 1 = 01 – α2 – βγ.Hence, Option (C) is the correct answer.

Q14 of 307 Page 6

If is such that A² = I, then

As A² = I,

So, α² + βγ = 1

α² + βγ – 1 = 0

1 – α² – βγ.

Hence, Option (C) is the correct answer.

If and and AB = I₃, then x + y equals

If and (A + B)² = A² + B², then values of a and b are

If S = [s_ij] is a scalar matrix such that s_ij = k and A is a square matrix of the same order, then AS = SA = ?

If A is a square matrix such that A² = A, then (I + A)³ – 7A is equal to
