1 Easy

1 of 1

Application +4 | -1

The combined equation of the two lines

a x+b y+c

=0

and

a^{\prime} x+b^{\prime} y+c^{\prime}=0

can be written as

(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

2 x^{2}+x y-3 y^{2}=0

View answer and explanation

Correct option: D

x^{2}-y^{2}-10 x y=0

Option D (

x^{2}-y^{2}-10 x y=0

) is correct because it represents the equation of the angle bisectors derived from the given equation.
