Vertices (6, 0), foci (4, 0).

Here, the vertices are on the x-axis.

Therefore, the equation of the ellipse will be of the form =1, where a is the semi-major axis.

Accordingly, a=6 and c = 4.

It is known that a² = b²+c².

6² = b²+4²

36 = b² + 16

b² = 36 – 16

b =

Thus, the equation of the ellipse is =1 or = 1.
