Question

Consider the quadratic equation in two variables
−44x2+40√3xy−4y2−256=0.

Choose the correct alternative:

a.θ=60∘ and represents a hyperbola.

B.θ=30∘ and represents two concurrent lines.

c.θ=30∘ and represents a point.

d.θ=60∘ and represents two concurrent lines.

e.θ=60∘ and represents a point.
