Calculate Hyperbola properties

\frac{( x - 2 ) ^{2}}{5} - \frac{( y + 1 ) ^{2}}{9} = 1 :

Right-left Hyperbola with

(h, k) = (2, - 1), a = 5, b = 3

= \frac{( 5 ) ^{2} + 3 ^{2}}{5}

ecce n t r i c i t y \frac{x ^{2}}{9} - \frac{y ^{2}}{4} = 1

ecce n t r i c i t y x^{2} - y^{2} = 25

ecce n t r i c i t y \frac{x ^{2}}{45} - \frac{y ^{2}}{216} = 1

ecce n t r i c i t y 16 x^{2} - 9 y^{2} - 64 x - 18 y + 199 = 0

ecce n t r i c i t y \frac{x ^{2}}{4} - \frac{y ^{2}}{16} = 1
