Extract

In the textbooks there are many examples concerning the leading features of the triangle whose sides are given by the equations ax2 + 2hxy + by2 = 0 and L ≡ lx + my + n=0. These are usually easy because of the use that can be made of the origin. But when we replace the first equation by the general equation

S ≡ ax 2 + 2hxy + by 2 + 2gx + 2fy + c = 0
