Answer 1

Answer:

Step-by-step explanation:

Let x__ and let

1 1 1 2 x x

P= 0 2 2 , Q= 0 4 0

0 0 3 x x 6

and R = PQP__

Then which of the following options is/are correct?

a =6 a,

b b

B. For x = 1, there exists a unit vector ___+___ +____ for which R= __ 0

__ = 0

__ 0

C. det R = det 2 x x + 8 , for all x x__

0 4 0

x x 5

D. There exists a real number x such that PQ = QP
