from the foci, it is clear that the center is at (6,1) and
c = 2
Since the major axis has length 10, a=5
b^2 = 25-4 = 21
so, the equation is
(x-6)^2/25 + (y-1)^2/21 = 1

Write the equation of the ellipse using the given information:
The ellipse has foci (4, 1) and (8, 1) and vertices (1, 1) and (11, 1);
