Please help! classify this conic equations:

1) $$x ^{2}+y ^{2}+2x+2y+1=0$$
2) $$2x ^{2}+2y ^{2}-4x+4y+19=0$$
3) $$x ^{2}+4y ^{2}=100$$
4) $$8x ^{2}-3y ^{2}=120$$
5) $$y= ^{2}-2x+3$$

do you know what a conic section is?

anonymous · Answer

not really, im starting this topic

asnaseer · Answer

ok, so first take a look here to familiarise yourself. you should then be able to answer this question yourself. if not, then post here which part you don't understand and I'll be more than glad to help. see here: http://en.wikipedia.org/wiki/Conic_section
