Write an equation of an hyperbola whose vertices are
(0,0)and(16,0), and whose foci are (18,0) and (-2,0).

Step-by-step explanation:

∵ The equation of a hyperbola along x-axis is,

Where,

(h, k) is the center,

a = distance of vertex from the center,

b² = c² - a² ( c = distance of focus from the center ),

Here,

vertices are (0,0) and (16,0), ( i.e. hyperbola is along the x-axis )

So, the center of the hyperbola = midpoint of the vertices (0,0) and (16,0)

= (8,0)

Thus, the distance of the vertex from the center, a = 8 unit

Now,  foci are (18,0) and (-2,0).

Also, the distance of the focus from the center, c =  18 - 8 = 10 units,

( Note : b ≠ -6 because distance can not be negative )

Hence, the equation of the required hyperbola would be,
