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).

why the angle to find slope in straight lines is always measured from positive side

Ashish Pal Student Expert 29th Nov, 2019

Hello dear aspirant.

It is a rule of mathematics. And rules are never to be challenged . Sometimes people interpret it that it's so because X positive is the positive real axis but it's not satisfactory reason. So we can say it's a conventional rule to be followed.

Hope you

You have enough marks in 12th for admission in good college in DU but if you do not have mathematics in your 12th then you can only get into B.Com Pass course at DU. For honors mathematics is mandatory for DU.
