The three lines given by the combined equation y^3-4 x^2 y=0 represents
Options
- Athe sides of an isosceles triangles
- Bthe sides of a right angled triangle
- Cthe side of an equilateral triangle
- Dconcurrent lines
Correct answer
D. concurrent lines
Step-by-step solution
Given equation, aligned y^3-4 x^2 y & =0 y(y-2 x)(y+2 x) & =0 y=0, y=2 x and y & =-2 x aligned Clearly, these lines meet at (0,0) : Lines are concurrent.
