If a variable chord of x2–y2=9 touches y2=12x and locus of middle po – InterviewSolution

1.	If a variable chord of x2–y2=9 touches y2=12x and locus of middle point of these chords is x3+λ1xy2+λ2y2=0, then the value of λ2−λ1 is
Answer» If a variable chord of $x^{2} - y^{2} = 9$ touches $y^{2} = 12 x$ and locus of middle point of these chords is $x^{3} + λ_{1} x y^{2} + λ_{2} y^{2} = 0$ , then the value of $λ_{2} - λ_{1}$ is
