Find the inverse of each of the matrices given below.
We have,
We have to find A-1 and
Firstly, we find |A|
Expanding |A| along C1, we get
= 8(0 – 6) – 10(-24 – 1) + 8(-24 – 0)
= 8(-6) – 10(-25) + 8(-24)
= -48 + 250 – 192
= 250 – 240
= 10
Now, we have to find adj A and for that we have to find co-factors:
Ans.
