If α and β are the roots of the equation x2 + x + 1 = 0, then find the equation with roots 2 α + β and α + 2 β

Detailed Solution for RRB ALP & Technician Mock Test (English) - 14 - Question 26

α + β = − 1 ; α β = 1

S ′ = 2 α + β + α + 2 β = 3 α + β = − 3 

P ′ = 2 α + β α + 2 β
= 2 α2 + 5 α β + 2 β2 
= 2 α2 + β2  + 5 α β
= 2 [ (α + β)2 − 2 α β ] + 5 α β
2 (α + β)2  + α β
= 2 (− 1)2 +1 = 3
required equation : x2 − S ′ x + P ′ = 0
