-9x^2+4y^2=36

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

(h, k) = (0, 0), a = 3, b = 2

Solution steps

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

Rewrite

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

in the form of a standard hyperbola equation

\frac{( y - 0 ) ^{2}}{3 ^{2}} - \frac{( x - 0 ) ^{2}}{2 ^{2}} = 1

Therefore Hyperbola properties are:

(h, k) = (0, 0), a = 3, b = 2

- 8 x^{2} + 2 y^{2} - 12 = 0

9 x^{2} - y^{2} + 6 y - 18 = 0

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

25 x^{2} + 246 x - 25 y^{2} - 13 y = 233

9 x^{2} - 4 y^{2} - 18 x + 16 y - 43 = 0
