Looking at the equation we can tell it will be an ellipse because of the coefficients of x^{2} and y^{2} are not the same but they are the same sign (so not a hyperbola). It's easiest to find the critical points like the center foci and vertices if it's written in the form: (x-h)^{2}/(a^{2})+(y-k)^{2}/(b^{2}) = 1

First we reorganize a little:

3x^{2}-36x+4y^{2}+24y = -132

Then we try to complete the square for x and y. We'll start with y:

3x^{2}-36x + 4(y^{2}+6x +9) = -132+36 (since we factored by 4)

3x^{2}-36x + (y+3)^{2} = -96

now for x:

3(x^{2}-12x+36)+4(y+3)^{2}=-96+108 (since I factored out a 3, we added 108 not 36)

3(x-6)^{2}+4(y+3)^{2}=12

Finally, we divide by 12 to get the right hand side equal to 1:

(x-6)^{2}/4 + (y+3)^{2}/3 = 1

Now we can read off the points you need:

The center is shifted from (0,0) to (6,-3) (this is from the h, k).

The major axis is√4 = 2 left and right from the center (since the larger number is under the x term we can tell it will be longer in the horizontal direction). So the major vertices are: (4,-3)) and (8,-3). The minor vertices are: (6,-3-√3) (6,3+√3)). The foci distance "c" is found by the ellipse relation: c^{2}=a^{2}-b^{2}. 4-3 = 1. so c = √1 = 1. Finally the foci points are a distance c from the center in the major axis direction: F1 = (5,-3) and F2 = (7,-3)
