The combined equation of the two lines a x+b y+c=0 and a^′ x+b^′ y+c^′=0 can be written as (a x+b y+c)(a^′ x+b^′ y+c^′)=0. The equation of the angle…

The combined equation of the two lines $\displaystyle a x+b y+c=0$ and $\displaystyle a^{\prime} x+b^{\prime} y+c^{\prime}=0$ can be written as $\displaystyle (a x+b y+c)\left(a^{\prime} x+b^{\prime} y+c^{\prime}\right)=0$.The equation of the angle bisectors of the lines represented by the equation $\displaystyle 2 x^2+x y-3 y^2=0$ is
