Question

The combined equation of the bisectors of the angle between the lines represented by $(x^{2} + y^{2})\sqrt{3} =$ $4xy$ is

• A. $y^{2} - x^{2} = 0$
• B. $xy = 0$
• C. $x^{2} + y^{2} = 2xy$
• D. $\frac{x^{2} - y^{2}}{\sqrt{3}} = \frac{xy}{2}$

Answer 1

Answer: (A)

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

Answer 2

$\frac{x^{2} - y^{2}}{\sqrt{3} - \sqrt{3}} = \frac{xy}{- 2} \Rightarrow x^{2} - y^{2} = 0$ .
