foci x^2-4y^2-2x+16y=20

foci

x^{2} - 4 y^{2} - 2 x + 16 y = 20

(\frac{7}{2}, 2), (- \frac{3}{2}, 2)

Solution steps

(h + c, k), (h - c, k)

Calculate Hyperbola properties

x^{2} - 4 y^{2} - 2 x + 16 y = 20 :

Right-left Hyperbola with

(h, k) = (1, 2), a = 5, b = \frac{5}{2}

(1 + c, 2), (1 - c, 2)

Compute

c :

c = 5^{2} + (\frac{5}{2})^{2} : \frac{5}{2}

(1 + \frac{5}{2}, 2), (1 - \frac{5}{2}, 2)

Refine

(\frac{7}{2}, 2), (- \frac{3}{2}, 2)

\frac{x ^{2}}{45} - \frac{y ^{2}}{360} = 1

\frac{y ^{2}}{225} - \frac{x ^{2}}{64} = 1

4 y^{2} - 9 x^{2} + 16 y + 18 x = 29

\frac{( x - 6 ) ^{2}}{4} - \frac{( y + 6 ) ^{2}}{81} = 1

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