How do use the discriminant test to determine whether the graph #9x^2+6xy+y^2+6x-22=0# whether the graph is parabola, ellipse, or hyperbola?
Let's set it up...
In the form that your section is in,
A = 9, B = 6, and C = 1.
These are the lead coefficients of
Since the discriminant is zero, this is a parabola.
