Find the eccentricity, co ordinates of foci-length of latus rectum and equation of directrices of the folloeing ellipses.
`9x^2+16y^2-36x+32y-92=0`

Text Solution

Verified by Experts

The correct Answer is:
`e=(sqrt(7))/(4)` foci `(2+- sqrt(7)-1)`,
Length of latus rectum =9/2. , Equation to direction `sqrt(7)=2 sqrt(7)+-16`
