How would I solve this:

Find a parametric equation for the conic section:

9x^2 - 18x + 6y^2 - 96y + 9 = 0

Thanks!

this is an ellepse

the equation is in the form of

you will need to complete the square to get it to this form

I was a not exactly sure what you meant by parametric equation

this is just a modified equation from standard form to make is easy to recognize the charactoristics. - December 4th 2009, 08:33 AMGrandad
Hello iheartyou119

Welcome to Math Help Forum!As bigwave has said, you'll need to complete the square to write the equation in a form suitable for parametric equations. This form is usually written:

Here's the first couple of lines showing you how to complete the square:

I think this an ellipse where the foci are paralel to the y axis

so the would be under the

I have tried this, and I still can't seem to get the right answer. The answer is supposed to be:

x = 1 + 4 cos t, y = 3 + 3 sin t - December 6th 2009, 11:09 PMGrandad

Yes, you are correct. The equation is supposed to be:

9x^2 - 18x + 16y^2 - 96y + 9 = 0
