So, over Spring Break, my teacher assigned this packet on conics. One of the parts of the packet is to "simplify" (Or rather elongate) the equation into general form. General form is ax^2+by^2+cx+dy+e=0, where A, B, C, D are all integers, and A is positive. Well, I did that to an equation, but for the x^2 term, I have a negative number, so I have no idea what to do. Do I just make it ay^2+bx^2, etc, etc. (Like I did). Or did I do something wrong? Forgot to add, this is happening on quite a few of them (1/3 of them about), so if this is wrong, then I'm basically screwed, and will get a bad grade on this project.
