Question

The equation 3x² - 3y² - 12x + 12y - 2 = 0 represents

• A. A parabola
• B. An ellipse
• C. A hyperbola
• D. A rectangular hyperbola

Answer 1

Answer: (D)

A rectangular hyperbola

Answer 2

Given equation can be written as $\frac { ( x - 2 ) ^ { 2 } } { 2 / 3 } - \frac { ( y - 2 ) ^ { 2 } } { 2 / 3 } = 1$

Clearly it represents a rectangular hyperbola.
