x^2-y^2=4

Solution

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

Solution

(h, k) = (0, 0), a = 2, b = 2

Solution steps

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

Rewrite

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

in the form of a standard hyperbola equation

\frac{( x - 0 ) ^{2}}{2 ^{2}} - \frac{( y - 0 ) ^{2}}{2 ^{2}} = 1

Therefore Hyperbola properties are:

(h, k) = (0, 0), a = 2, b = 2

Popular Examples

foci (x^2}{81}+\frac{y^2)/9 =1 foci

\frac{x ^{2}}{81} + \frac{y ^{2}}{9} = 1

16x^2+16y^2+32x+8y=47

16 x^{2} + 16 y^{2} + 32 x + 8 y = 47

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

\frac{x ^{2}}{9} + \frac{y ^{2}}{4} = 1

directrix y^2=-16x directrix

y^{2} = - 16 x

foci (x^2)/(49)+(y^2)/(36)=1 foci

\frac{x ^{2}}{49} + \frac{y ^{2}}{36} = 1
