Thread: Analytic Geometry- Analyse y^2 + 6y +2x + 1 = 0

Hello,

I need help with this problem:

Analyze the equation y^2 + 6y +2x + 1 = 0

By analyze the problem means to find the center, foci, and vertices.

I do not know how to get this equation into standard form. (I believe that is the goal.)

Please help me.

This is a quadratic. What information can you gain now?

Well for this equation I would complete the square. I belive standard form of an elipse will be the result. I do not know how to do this.

Is that basically what you did?

I have ALREADY completed the square to give you a QUADRATIC in standard form. A Quadratic is NOT an Ellipse.

If you cannot recognise that post # 2 explicitly shows a (sideways) parabola then you need to go back and thoroughly revise your class notes and textbook.
