Question

The equation of the bisectors of angle b/w the lines represented by the equation

2 −

2 = 0,

is-

A] = 0 B] = 0 C] = 0 D] none​

Answer 1

Answer:

Equation of bisectors of angle between the pair of straight line ax

2

+2hxy+by

2

=0 is given by

a−b

x

2

−y

2

=

h

xy

⇒hx

2

−(a−b)xy−hy

2

=0

Here coefficient of x

2

+ coefficient of y

2

=h+(−h)=0

∴ above equation represent the pair of ⊥er lines

Hence choice (a) is correct.
