foci y^2=x^2-8

Solution

foci

y^{2} = x^{2} - 8

Solution

(0, 4), (0, - 4)

Solution steps

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

Calculate Hyperbola properties

y^{2} = x^{2} - 8 :

Up-down Hyperbola with

(h, k) = (0, 0), a = 22, b = 22

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

Compute

c :

c = (22)^{2} + (22)^{2} : 4

(0, 0 + 4), (0, 0 - 4)

Refine

(0, 4), (0, - 4)

Popular Examples

foci (x^2)/(36)-(y^2)/(13)=1 foci

\frac{x ^{2}}{36} - \frac{y ^{2}}{13} = 1

foci ((x+2)^2}{16}-\frac{(y-1)^2)/9 =1 foci

\frac{( x + 2 ) ^{2}}{16} - \frac{( y - 1 ) ^{2}}{9} = 1

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

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

foci (x^2)/(36)-(y^2)/(25)=1 foci

\frac{x ^{2}}{36} - \frac{y ^{2}}{25} = 1

foci y^2-4x^2=36 foci

y^{2} - 4 x^{2} = 36
