বইমেলা paragraph??????​

Answer 1

Explanation:

As the given matrices are equal, their corresponding elements are also equal. Comparing the corresponding elements, we get:

x+y=6,xy=8,5+z=5

Now, 5+z=5⇒z=0

We know that:

(x−y)

2

=(x+y)

2

−4xy

⇒(x−y)

2

=36−32=4

⇒x−y=±2

Now, when x−y=2 and x+y=6, we get x=4 and y=2

When x−y=−2 and x+y=6, we get x=2 and y=4

∴x=4,y=2 and z=0orx=2,y=4 and z=0
