Homework Statement
Let C be the curve whose equation is given by: 4x^2+18y-20=9y^2+16x+9Identify and sketch the curve C and if possible give its center, directrix, foci, vertices, and endpoints on the minor axis.
Homework Equations
I have learned parabola, hyperbola and elispes (these are conic sections)
The Attempt at a Solution
To start with, I really can't. I tried to rearrange the equations.
4x^2 - 9y^2+18y-16x=29
but i don't see how i can graph this... please guide me through this, thank you.

i just asked wolfram to do graph 4x^2 - 9y^2+18y-16x=29 and i got two hyperbolas (they are not symmetrics)... but how come? i don't see the 1 in any side
