My teacher says I'm getting close to the answer but not there yet.
4x^(2) + 9y^(2) + 8x + 18y -23 = 0
Identify the vertices, co-vertices, foci, length of the major axis, and length of the minor axis.
I just really need to get the standard form. I'm getting
(x+1)/2)^(2) + (y+1)/3) ^(2) = 36
Thanks so much !!!!=) Haha I can't wait til summer!
