Joint Equation of A Pair of Straight Lines
Joint Equation of A Pair of Straight Lines The joint equation of the straight lines a₁x + b₁y + c₁ = 0 and a₂x + b₂y + c₂ = 0 is (a₁x + b₁y + c₁) (a₂x + b₂y + c₂) = 0 a₁a₂x² + xy (a₁b₂ + a₂b₁) + b₁b₂y² + (a₁c₂ + a₂c₁) Read more about Joint Equation of A Pair of Straight Lines[…]
