Completing the squares for x and y, and dividing through by 36, yields
[(x - 1)/2]^2 + [(y + 1)/3]^2 = 1.
This is an ellipse, with centre (1, -1).

The equation of the conic is
9x² + 4y² - 18x + 8y = 23
9x² - 18x + 4y² + 8y = 23
9(x² - 2x + 1) + 4(y² + 2y + 1) = 23 + 9*1 + 4*1
9(x - 1)² + 4(y + 1)² = 36
(x - 1)²/4 + (y + 1)²/9 = 1
This is the equation of an ellipse with center (1, -1).

The equation of the conic is: 4x² - 16x + 16y + 32 = 0 x² - 4x + 4y + 8 = 0 x² - 4x = -4y - 8 x² - 4x + 4 = -4y - 8 + 4 (x - 2)² = -4y - 4 (x - 2)² = -4(y + one million) The conic is a parabola. Its vertex is (2, -one million).
