If 1, omega,omega^(2) are the cube roots...

If `1, omega,omega^(2)` are the cube roots of unity then the vlue of m for which the matrix `[(1,omega,m),(omega,m,1),(m,1,omega)]` is singular, is -

A

`lamda!=-2`

B

`lamda!=2`

C

`lamda!=3`

D

`lamda!=-3`

Text Solution

Verified by Experts

The correct Answer is:
x + 2y + 3z = 1, 3x - 2y + z = 2, 4x + 2y + z = 3, `x = (7)/(10), y = (3)/(40), z = (1)/(20)`
