Question

Find the joint equation of the following pair of lines : 
$$2 x + y = 0 \text { and } 3 x - 5 y = 0$$


Solution

soln :
Eqn of first line $$ \Rightarrow 2x+y = 0$$
Eqn of second line $$ \Rightarrow  3x-5y = 0$$
Thus the joint equations of a line is gn by
$$ (2x+y)(3x-5y) = 0$$
$$ 2x(3x-5y)+y (3x-5y) =0$$
$$ 6x^{2}-10xy + 3xy - 5y^{2} = 0 $$
$$ \therefore 6x^{2}-7xy -5y^{2} = 0$$
This is the required joint eqn
