foci 3x^2+7y^2-21=0

Solution

foci

3 x^{2} + 7 y^{2} - 21 = 0

Solution

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

Solution steps

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

Calculate ellipse properties

3 x^{2} + 7 y^{2} - 21 = 0 :

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 9x^2+6y^2+36y=0 foci

9 x^{2} + 6 y^{2} + 36 y = 0

foci ((x-1)^2}{12}+\frac{y^2)/8 =100 foci

\frac{( x - 1 ) ^{2}}{12} + \frac{y ^{2}}{8} = 100

foci (x^2)/(64)+(y^2)/(81)=1 foci

\frac{x ^{2}}{64} + \frac{y ^{2}}{81} = 1

foci x^2+y^2-8x-20y+115=0 foci

x^{2} + y^{2} - 8 x - 20 y + 115 = 0

foci 9x^2+16y^2-18x-64y-71=0 foci

9 x^{2} + 16 y^{2} - 18 x - 64 y - 71 = 0
