Question 1010718

identify the conic section if it is a parabola give the vertex if it is a circle give the center and radius if it is a ellipse or a hyperbola give the center and foci 
5x^2-5y^2+40x-20y+35=0
<pre>This is INDEED a HYPERBOLA, since higher-degree x and y have different signs.
However, that person is WRONG, as usual, because the equation you're looking for is: {{{highlight_green(matrix(1,3, ((x + 4)^2)/5 - ((y + 2)^2)/5, "=", 1))}}}
