1.If α,β\alpha, \betaα,β and γ\gammaγ are three consecutive terms of a non-constant G.P. such that the equations αx2+2βx+γ=0\alpha x^2 + 2\beta x + \gamma = 0αx2+2βx+γ=0 and x2+x−1=0x^2 + x - 1 = 0x2+x−1=0 have a common root, then α(β+γ)\alpha(\beta + \gamma)α(β+γ) is equal to:a.βγ\beta\gammaβγb.αβ\alpha\betaαβc.αγ\alpha\gammaαγd.000Login to continueOnly logged in users canattempt or see the solution.
