You have a quadratic equation in x and y in general form. It could be a hyperbola. You can convert the equation to standard form if you are not sure about its being a hyperbola. A bit of rearrangement with commutativity and inverses gives , and then you can complete the square for x.
, and this seems to be a hyperbola, based on subtraction of y^2 term but addition of x^2 term.
- , hyperbola in standard form.
