Question

What conic section is the equation below?
2x^2+15x+4y+9x=4x^2

Answer 1

notice, you only have an "x" squared, no a "y" squared", so that'd give tell you something

Answer 2

ellipses, or circles( which are just round ellipses), have a squared "x" and "y", both positive or negative

hyperbolas, have a squared "x" and "y", either of them is negative

so.. what's left?

Answer 3

well my guess was a parabola

Answer 4

yeap, when you have only either "x" or "y" ONLY squared, is a giveaway is a parabola

Answer 5

Answer 8

when the "x" is squared, is vertical
when the "y" is squared, is horizontal
