Find the equation of pair of straight lines that bisect the angles between the lines represented by (a x^2+2 h x y+b y^2=0 ).
Options
- A( x^2+y^2 a+b = x y h )
- B( x^2+y^2 a-b = x y h )
- C( x^2+y^2 a-b = h x y )
- D( x^2-y^2 a-b = x y h )
Correct answer
D. ( x^2-y^2 a-b = x y h )
Step-by-step solution
The equation of pair of straight lines that bisect the angles between the lines represented by ( aligned a x^2+2 h x y+b y^2 & =0 is x^2-y^2 a-b & = x y h aligned ) Hence, option (d) is correct.
