<h3>How to determine the ellipse equation?</h3>
The given parameters are:
- Foci: (-4, 0) and (4, 0)
- Length of major axis = 14
The above means that:
c = 4 and
The semi-major axis, a = 7 i.e 14/2
Calculate b using

So, we have:


Square both sides

The standard form of the ellipse is represented as:

This gives

Evaluate

Hence, the equation of the ellipse is
