foci 7x^2=21-3y^2

Solution

foci

7 x^{2} = 21 - 3 y^{2}

Solution

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

Solution steps

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

Calculate ellipse properties

7 x^{2} = 21 - 3 y^{2} :

Ellipse with center

(h, k) = (0, 0), b = 7, a = 3

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

Compute

c :

c = 7^{2} - 3^{2} : 2

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

Refine

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

Popular Examples

foci 9x^2+25y^2+18x+50y-191=0 foci

9 x^{2} + 25 y^{2} + 18 x + 50 y - 191 = 0

foci 3x^2+4y^2-16x+16=0 foci

3 x^{2} + 4 y^{2} - 16 x + 16 = 0

foci 3x^2-6x+y^2+4y-11=0 foci

3 x^{2} - 6 x + y^{2} + 4 y - 11 = 0

foci 5x^2+2y^2=5 foci

5 x^{2} + 2 y^{2} = 5

foci 4x^2+8x+2y^2+16y=-28 foci

4 x^{2} + 8 x + 2 y^{2} + 16 y = - 28
