Q. 8
Mark the Correct alternative in the following:
If α, β are the roots of the equation 
the roots of the equation 
, then 
A. 
B. 
C. 
D. none of these
Answer :
α2 + pα + 1 = 0, β2 + pβ + 1 = 0
α + β = -p, αβ = 1
γ2 + qγ + 1 = 0, δ2 + qδ + 1 = 0
δ – γ = 
, γδ = 1
(α – γ)(α + δ)(β – γ)(β + δ)
= (α2 + α(δ – γ) – γδ)(β2 + β(δ – γ) – δγ)
