Final answer:

The equation represents an ellipse with a center at (0, 0), a major axis along the x-axis, and a minor axis along the y-axis. The distances between the center and the vertices along the major and minor axes are 8 and approximately 4.62, respectively.

Step-by-step explanation:

The equation x² - 2xy + 4y² = 64 represents a quadratic equation in two variables, x and y. This equation can be simplified by completing the square to obtain (x - y)² + 3y² = 64. From this equation, we can understand the following information:

  1. The graph of this equation will be a conic section, specifically an ellipse, since the coefficients of x² and y² are positive.
  2. The center of the ellipse is at the point (0, 0) since the equation contains only even powers of x and y.
  3. The major axis of the ellipse is along the x-axis, and the minor axis is along the y-axis since the coefficient of x² is larger than the coefficient of y².
  4. The distance between the center of the ellipse and the vertex along the major axis is equal to the square root of 64, which is 8.
  5. The distance between the center of the ellipse and the vertex along the minor axis is equal to the square root of 64/3, which is approximately 4.62.
