Coordinate Geometry Problems

Hello!!,

Here's a sample problem: (Ellipse) (I have no idea)

"Passing through (2,3), Center at the origin, Latus rectum three times the distance from center to focus"

*i tried to manipulate the LR eqn (2b^2/a) and substituting the x&y to the eqn of the ellipse but I cant Get the formulas X( *

Thanks in advance for leaving a reply :)

Hello,

sorry that I skipped an important step. Here we go (you remember: a must be positive!):

Multiply through the complete equation by a:

Divide the complete equation by 3aČ:

For the following steps see my previous posts.
