The given equation is ellipse.

Given -

$x^2+4y^2+2x-24y+33=0$

Conic section formula, in the general form, could be written like this-

$ax^2+cy^2+dx+ey+f=0$

The apply the following conditions to identify the equation.

If $a=c$ , It is a circle.
If $a xx c = 0$ , it is a parabola
If $a xx c > 0$ , it is ellipse .
If $a xx c< 0$ , it is a hyperbola

In our case

$a=1; c=4$

$1 xx 4 = 4 >0$ , then the given equation is ellipse.
