foci 5x^2+9y^2+30x=0

Solution

foci

5 x^{2} + 9 y^{2} + 30 x = 0

Solution

(- 1, 0), (- 5, 0)

Solution steps

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

Calculate ellipse properties

5 x^{2} + 9 y^{2} + 30 x = 0 :

Ellipse with center

(h, k) = (- 3, 0), a = 3, b = 5

(- 3 + c, 0), (- 3 - c, 0)

Compute

c :

c = 3^{2} - 5^{2} : 2

(- 3 + 2, 0), (- 3 - 2, 0)

Refine

(- 1, 0), (- 5, 0)

Popular Examples

foci (x^2}{64}+\frac{y^2)/9 =1 foci

\frac{x ^{2}}{64} + \frac{y ^{2}}{9} = 1

foci (x^2)/(20)+(y^2)/(36)=1 foci

\frac{x ^{2}}{20} + \frac{y ^{2}}{36} = 1

foci (x^2}{12}+\frac{y^2)/6 =1 foci

\frac{x ^{2}}{12} + \frac{y ^{2}}{6} = 1

foci ((x+4)^2)/(25)+((y-1)^2)/(16)=1 foci

\frac{( x + 4 ) ^{2}}{25} + \frac{( y - 1 ) ^{2}}{16} = 1

foci ((x-4)^2)/9+((y-1)^2)/(25)=1 foci

\frac{( x - 4 ) ^{2}}{9} + \frac{( y - 1 ) ^{2}}{25} = 1
