## Homework Statement

What is the difference in these equations?

1. 4(x-1)^2)+(y+2)^2=0

2. (((x-1)^2)/4)+(((y+2)^2)/16)=1

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

## Homework Equations

-None-

## The Attempt at a Solution

If you are wondering where i got these equations from where by changing the constant to +8, and +10 from -8 for this equation:

4x^2+y^2-8x+4y-8=0

I think the first one is a circle because it kind of looks like x^2+y^2=r^2, not sure..

The second one is just a basic ellipse because it follows its standard form.

The third one is a hyperbola because it is x^2-y^2
