Trace the conic? 8x^2+4xy+5y^2=24(x+y)

Avishek Dutta 29th Nov, 2019

ax^2+2hxy+by^2+2gx+2fy+c=0.
8x^2+4xy+5y^2-24x-24y=0
a=8,b=5,c=0,h=2,f=g=-12
D=abc+2fgh-af^2-bg^2-ch^2
=8*5*0+2*(-12)(-12)*2-8*(-12)^2-5*(-12)^2-0*2^2
=-1296
Now
If D=0

If h^2-ab > 0,the equation represents two distinct real lines.
If h^2-ab = 0,the equation represents parallel lines.
If h^2-ab < 0,the equation represents non-real lines.

If D is non zero

If h^2-ab>0,it represents a hyperbola and a rectangular hyperbola(a+b=0).
