Question
If α, β & γ are the roots of the equation x3 + px + q = 0, then the value of the determinant
=
Options
A.p
B.q
C.p2 - 2q
D.none
Solution
α, β, γ are roots of x3 + px + q = 0
∴ α + β + γ = 0 Here
Applying C1 → C1 + C2 + C3
(α + β + γ)
= 0
∴ α + β + γ = 0 Here
Applying C1 → C1 + C2 + C3
(α + β + γ)
