a^2-b^2=21

Solution

a^{2} - b^{2} = 21

Solution

(h, k) = (0, 0), a = 21, b = 21

Solution steps

a^{2} - b^{2} = 21

Rewrite

a^{2} - b^{2} = 21

in the form of a standard hyperbola equation

\frac{( a - 0 ) ^{2}}{( 21 ) ^{2}} - \frac{( b - 0 ) ^{2}}{( 21 ) ^{2}} = 1

Therefore Hyperbola properties are:

(h, k) = (0, 0), a = 21, b = 21

Popular Examples

a^{2} - b^{2} = 16

y/3 =(x^2)/(2+y)

\frac{y}{3} = \frac{x ^{2}}{2 + y}

5 y^{2} - 4 x^{2} - 20 = 0

(x^2)/(81)-(y^2)/(49)=1

\frac{x ^{2}}{81} - \frac{y ^{2}}{49} = 1

x^2-4y^2+2x-16y-4=0

x^{2} - 4 y^{2} + 2 x - 16 y - 4 = 0
