Which of the following matrices satisfies the equation `A^(2)+A=O` ?

A

`A={:((1,0),(0,1)):}`

B

`A={:((-1,0),(0,-1)):}`

C

`A={:((-1,-1),(-1,-1)):}`

D

`A={:((1,1),(1,1)):}`

Text Solution

Verified by Experts

The correct Answer is:
B
(i) Take A as common.
(ii) `A^(2)+A=0rArrA(A+I)=0`
(iii) From the options `A!=0,A+I=0`.
