What is the equation of the ellipse with foci (2, 0), (-2, 0) and vertices (7, 0), (-7, 0)
***
Given ellipse has a horizontal major axis
It standard form of equation: , a>b, (h,k)=(x,y) coordinates of center
For given ellipse:
center: (0,0)
a=7 (distance from center to vertices)
a^2=49
c=2 (distance from center to foci)
c^2=4
c^2=a^2-b^2
b^2=a^2-c^2=49-4=45
Equation of given ellipse:
