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

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

(h, k) = (2, - 2), a = 3, b = 3

Solution steps

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

Rewrite

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

in the form of a standard hyperbola equation

\frac{( x - 2 ) ^{2}}{3 ^{2}} - \frac{( y - ( - 2 ) ) ^{2}}{3 ^{2}} = 1

Therefore Hyperbola properties are:

(h, k) = (2, - 2), a = 3, b = 3

\frac{( x - 3 ) ^{2}}{4} - \frac{( y - 2 ) ^{2}}{12} = 1

4 x^{2} - 9 y^{2} - 16 x + 18 y + 11 = 0

\frac{( y + 1 ) ^{2}}{9} - \frac{( x + 3 ) ^{2}}{4} = 1

16 x^{2} - 64 x - 9 y^{2} - 54 y + 1 = 0

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

What is ((x-2)^2)/9-((y+2)^2)/9 =1 ?
The solution to ((x-2)^2)/9-((y+2)^2)/9 =1 is Hyperbola with (h,k)=(2,-2),a=3,b=3
