Find the equation for the ellipse that satisfies the given conditions:Length of major axis 26, foci `(+-5,0)`

Text Solution

Verified by Experts

Equation of ellipse can be given as
`x^2/a^2+y^2/b^2 = 1`
Here, Foci of ellipse ` = (+-5,0)`
So, `X`-axis is major axis and `c = 5`
Length of major axis `= 26`
`2a = 26=> a = 13`
`:. b^2 = c^2-a^2 = 169-25 = 144`
