In a second degree general equation, first the discriminant and determinant need to be examined.
if ? ≡ abc + 2fgh − af2 − bg2 − ch2 = 0 then the equation represents a pair of straight lines.
If not zero, then we examine the discriminant(D): (2h)^2-4ab = 4(h^2-ab)
- If the D=0, then it represents a parabola.
- if D<0 and h≠0 and a≠b, then it is an ellipse.
- if D<0 and h=0 and a=b, then it is a circle.
- if D>0 then it is a hyperbola. if a+b=0, then it is a rectangular hyperbola.
After analysing this, we proceed to the solutions accordingly.
