Question

Which conic section does this equation match?
x^2-4x+y^2+6y-9=5
My guess is its a circle

Answer 1

RIght, it would be a circle. Which is a special case of an ellipse if you specially had to mention one of the conic sections. Would you know how to show it if needed, though?

Answer 2

*specifically

wow, I r iz english suck -_-

Answer 3

well if I had to prove that it was a circle I would just compete the square with the equation given.
Which is (x-2)^2+(y+3)^2=9

Answer 4

Okay, awesome. Just making sure :)

Answer 5

Center is (2,-3) and the radius is 3:)
