Answer:
The correct answer is =
A +
<em> </em>I
Step-by-step explanation:
Since A is an n × n invertible non singular matrix, exists.
Given equation is + 3A -4I = O where I and O are the n × n identity and zero matrix respectively.
⇒ + 3A -4I = O
⇒ (
+ 3A -4I ) =
× O
⇒ AA + 3
A - 4
I = O
⇒ A + 3I - 4 = O
⇒ A + 3I = 4
⇒ =
A +
<em> </em>I
Thus the value of can be given by the above equation.
