Answer 2

Answer:

$\bold\red{x=4\:and\:y=-1}$

Step-by-step explanation:

It is a question of the product of matrices.

It is of (2×2) type that is two rows and two columns.

Given, that A and B are two matrices, and

${A}^{2}=B$

First of all we find ${A}^{2}$

Then, we equate it with matrix B.

Comparing the terms, we get

4x = 16 and -y = 1

Hence,

x = 4 and y = -1
