User: Identify this conic section for x 2 - 4x + y 2 - 4y + 4 = 12

Weegy: x^2 - 4x + y^2 - 4y + 4 = 12; it can be written to be: (x - 2)^2 + (y - 2)^2 = 16 thus it is a circle.

User: Identify this conic section. x 2 - y 2 = 16

Weegy: x^2 - 4x + y^2 - 4y + 4 = 12 can be written as (x - 2)^2 + (y - 2)^2 = 16; it is a circle with center (2, 2) and radius 4.

x^2 - y^2 = 16 can be rewritten as x^2/4^2 - y^2/4^2 = 1
therefore, the conic section for x^2 - y^2 = 16 is Hyperbola.

9x^2 + 4y^2 = 36 dividing 36 on both sides we get:
x^2/2^2 + y^2/3^2 = 1.
Therefore, the conic section for 9x^2 + 4y^2 = 36 is Ellipse.
