Question 307008: I cannot figure this out it's stressing me out.....I hope u can help me. PLEASE
16y^2-9x^2+36x-32y-164=0 I need to know the coordinates, and if its hyperbolic(center and focci) circular (center and vertex) elliptical(center and focci) parabolic(vertex and focus). Please please explain. Thank you

You need to complete the square in x and y.

Unequal coefficients for and and unequal signs are the signs of a hyperbola.
There now you can solve for center and foci.

Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
this is a hyperbola (second order terms, squares, have different signs)

isolating the squares will make it more recognizable

16y^2 - 32y + 16 - 9x^2 + 36x - 36 - 144 = 0

16(y - 1)^2 - 9(x - 2)^2 = 144

{[(y - 1)^2] / 9} - {[(x - 2)^2] / 16} = 1
