foci 9x^2+7y^2-63=0

Solution

foci

9 x^{2} + 7 y^{2} - 63 = 0

Solution

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

Solution steps

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

Calculate ellipse properties

9 x^{2} + 7 y^{2} - 63 = 0 :

Ellipse with center

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

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

Compute

c :

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

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

Refine

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

Popular Examples

foci 16x^2+64y^2=128 foci

16 x^{2} + 64 y^{2} = 128

foci ((x^2)/4)+y^2=1 foci

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

foci 4x^2+y^2-8x-4y-8=0 foci

4 x^{2} + y^{2} - 8 x - 4 y - 8 = 0

foci ((x-1)^2)/5+((y-3)^2)/4 =1 foci

\frac{( x - 1 ) ^{2}}{5} + \frac{( y - 3 ) ^{2}}{4} = 1

foci (2x^2)/(25)+((y-3)^2)/(49)=1 foci

\frac{2 x ^{2}}{25} + \frac{( y - 3 ) ^{2}}{49} = 1
