guys answer it quickly plzzzzzzzzzz
Given that A =[ 5 7 3
1 5 2
3 2 1] and
A³-KA²+lA=I then
(a) k=1
(b) l=15
(c) k=-11
(d)l=10
multiple choice (Q)​

Answer 1

Step-by-step explanation:

Here,

If A = 1

Then,

A³ - kA² + IA = l

1³ - 1x1² + 10x 1 = 15

10 = 15

Answer 2

Answer:

=> 93K = 1023

=> K= 11

=> L= 15

K + L = 11 + 15 = 26
