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

Solution

foci

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

Solution

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

Solution steps

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

Calculate ellipse properties

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

Ellipse with center

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

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

Compute

c :

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

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

Refine

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

Popular Examples

foci x^2+y^2+10x-6y+33=0 foci

x^{2} + y^{2} + 10 x - 6 y + 33 = 0

foci ((x-2)^2}{36}+\frac{(y-6)^2)/4 =1 foci

\frac{( x - 2 ) ^{2}}{36} + \frac{( y - 6 ) ^{2}}{4} = 1

foci 4x^2+y^2-48x+4y+48=0 foci

4 x^{2} + y^{2} - 48 x + 4 y + 48 = 0

foci 7x^2=14-2y^2 foci

7 x^{2} = 14 - 2 y^{2}

foci 25x^2+4y^2-100=0 foci

25 x^{2} + 4 y^{2} - 100 = 0
