1.	If α,β and γ are three consecutive terms of a non-constant G.P. such that the equations αx2+2βx+γ=0 and x2+x–1=0 have a common root, then α(β+γ) is equal to :
Answer» If $α, β$ and $γ$ are three consecutive terms of a non-constant G.P. such that the equations $α x^{2} + 2 β x + γ = 0$ and $x^{2} + x - 1 = 0$ have a common root, then $α (β + γ)$ is equal to :
