    Unhappy Types of Conics.

    I really need help with this so if anyone could please help me, that'd be awsome. . . here's the problem.


    Indicate which type of conic each of the following represents.

    1. (x-3)^2/9 + (y-2)^2/4 =1

    2.(x+2)^2/25 - (y-1)^2/9 =1

    See Conic section - Wikipedia, the free encyclopedia

    When looking at it your equations disregard (for purposes of identification) the offsets on x and y. For example, whatever (x-3)^2/9 + (y-2)^2/4 =1 is, is just a shifted version of x^2/9 + y^2/4 =1 (shifted 3 to the right and 2 up).

    2.(x+2)^2/25 - (y-1)^2/9 =1

    1. \frac{(x-3)^2}{9} + \frac{(y-2)^2}{4} =1<br />
 ellipse..

    2. \frac{(x+2)^2}{25} - \frac{(y-1)^2}{9} =1 hyperbola

    Compare:

    ellipse with center C(h, k) and the semi-axes a and b: \frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2}=1

    hyperbola with center C(h, k) and the semi-axes a and b: \frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2}=1
