hello dear

ax²+ by²+ 2hxy + 2yx +2fy +C = 0

above is a genral equation......

this equation can represent the particular equations it depends upon the conditions on it..

it can represent::

1.pair of staright lines

2.circle

3.ellipse

4.parabola

5.hyperbola

note::

see the condition from the relevant sources like SL loney,arihant
