Question 7324: Dear Sir/Madam,
I am confronted with the following problem:
"Find a polar equation which has the same graph as the
equation +x%5E2+-+2x+%2B+y%5E2+=+0+."
I assumed that this question wants you to complete the square, so I went ahead and did that.
1) +%28x-1%29%5E2+-+1+%2B+y%5E2+=+0+
2) +y%5E2+-+1+=+-%28x-1%29%5E2+
Meaning that the center of this circle is at (1, 1) correct? Either way, once you have this information, how do you put this into a polar equation? Or did I approach this question entirely wrong?
Thanks in advance.
Regards,
-Mike

Question 9378: Here is the second problem that I was talking about in another submitted question. A friend of mine thinks that the answer that we found to this question is wrong, but if it is than I don't know how to solve it. Could you help us. It is also a elipse problem that reads-
Graph the equation and find the coordinates of the foci.
(25x^2)-(144Y^2)= 3600
I think that there might be a mistake in this problem, but what do I know? That's why I'm asking you.

Question 9377: My friend and I think that the answer to this problem is wrong and we would like a second opinion. There are actually two problems, but I will post it on another seperate page. Its and elipse problem. It reads -
Graph the ellipse and find the foci. Here is the equation - (9x^2)+(4y^2)= 9
Our disagreement is over the coordinates in which the foci are located?
Could you please help us?

Question 12488: I am trying to find the vertex and intercepts so that I can graph the parabols I have gotten this far and my mind has gone totally blank.

the equation reads ----- y = x^2 +2x -3
-b/2a = -2/3
when I insert in the equation I get 4/9 + 24/9 - 33/9
which gives me -5/9
now I am lost
