Question: what is the difference between standard and general form of a circle?
Answer: 2) The general form : x2 + y2 + Dx + Ey + F = 0, where D, E, F are constants. If the equation of a circle is in the standard form, we can easily identify the center of the circle, (h, k), and the radius, r . ... In an equation, if the sign preceding h and k , ( h, k) are negative, then h and k are positive.
