foci x^2+y^2+4y=0

Solution

foci

x^{2} + y^{2} + 4 y = 0

Solution

(0, - 2), (0, - 2)

Solution steps

(h, k + c), (h, k - c)

Calculate ellipse properties

x^{2} + y^{2} + 4 y = 0 :

Ellipse with center

(h, k) = (0, - 2), b = 2, a = 2

(0, - 2 + c), (0, - 2 - c)

Compute

c :

c = 2^{2} - 2^{2} : 0

(0, - 2 + 0), (0, - 2 - 0)

Refine

(0, - 2), (0, - 2)
