b=3, c=4, centre at origin , foci on the x axis.

Explanation

To find the equation of the ellipse given the parameters \( b = 3 \), \( c = 4 \), center at the origin, and foci on the x-axis, we can follow these steps:

### Step 1: Identify the parameters
We know that:
- \( b = 3 \) (semi-minor axis)
- \( c = 4 \) (distance from the center to each focus)
- The center of the ellipse is at the origin (0, 0).
- The foci are on the x-axis, which means the major axis is horizontal.
