SUMMARY

The general equation of a parabola is represented as Ax² + Bxy + Cy² + Dx + Ey + F = 0. This equation is derived from the general quadratic equation, which can also describe ellipses, circles, and hyperbolas based on the values of coefficients A, B, and C. Specifically, for a conic section to be classified as a parabola, the condition B² = 4AC must be satisfied. Understanding this derivation is essential for recognizing the properties and classifications of conic sections.

I read a Wikipedia article titled "Parabola" that listed an equation of the form:

Ax2 + Bxy + Cy2 + Dx + Ey + F = 0

How is this derived? or where did it come from?

This probably should be under the General Math section of the forums. The equation that you posted is the general quadratic equation and depending of the values of A, B, and C it can either produce parabolas, ellipses, circles, or hyperbolas (excepting a few degenerate cases). If it is a parabola then B2 = 4(A)(C).
