Question

Let 4x^2 + 9y^2 + 8x + 18y - 23 = 0 be the equation of a conic section. Classify the conic section defined by this equation, write the standard equation of this conic section, and sketch the graph.

Answer 1

I believe this is an ellipse.

Answer 2

If you complete the square you should be able to get to
(x - h)^2/a^2 + (y-k)^2/b^2 = 1

Answer 3

alright thanks. i appreciate

Answer 4

yw

Answer 5

Common sense, since both coeff. of x² > 0 and y² > 0 . Thus it's Ellipse.
