Question

a matrix A = (2 -2) and A²= pA. write the value of p

Answer 1

Hope this helps ,I have taken the elements as 2 and -2

Answer 2

Considering A = [2   -2]

Step-by-step explanation:

Given that A²= pA,

A² = A x A

A² = [2   -2] x [2   -2]

Error Multiplication can only happen if

m x n = n x t

resulting matrix will be m x t.

For eg : 1 x 2 = 2 x 1

so the the resulting matrix will be 1 x 1.
