9x^2-9y^2=9

9 x^{2} - 9 y^{2} = 9

(h, k) = (0, 0), a = 1, b = 1

Solution steps

9 x^{2} - 9 y^{2} = 9

Rewrite

9 x^{2} - 9 y^{2} = 9

in the form of a standard hyperbola equation

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

Therefore Hyperbola properties are:

(h, k) = (0, 0), a = 1, b = 1

(x + y) (x - y) = 119

y^{2} - 4 x^{2} - 4 y + 24 x = 48

x^{2} - 4 y^{2} + 2 x - 16 y - 19 = 0

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

6 x^{2} - 3 y^{2} + 36 x + 30 y = 39
