x^2-4y^2+2x-8y-19=0

x^{2} - 4 y^{2} + 2 x - 8 y - 19 = 0

(h, k) = (- 1, - 1), a = 4, b = 2

Solution steps

x^{2} - 4 y^{2} + 2 x - 8 y - 19 = 0

Rewrite

x^{2} - 4 y^{2} + 2 x - 8 y - 19 = 0

in the form of a standard hyperbola equation

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

Therefore Hyperbola properties are:

(h, k) = (- 1, - 1), a = 4, b = 2

x^{2} - y^{2} - 8 x + 2 y + 14 = 0

9 x^{2} - y^{2} + 54 x + 10 y + 55 = 0

4 x^{(2)} - 25 y^{(2)} + 16 x + 50 y - 109 = 0

x^{2} + 12 = y^{2} + 6 x - 2 y

- 36 x^{2} + 25 y^{2} = 900
