Example 6 Find the equation of the parabola with focus (2, 0) and directrix x = 2. Since focus lies on x-axis Hence equation is either y2 = 4ax or y2 = 4ax Now focus has positive x co-ordinate So, we have to use equation y2 = 4ax Coordinates of focus = (a, 0) (2, 0) = (a, 0) Hence a = 2 Required equation is y2 = 4ax y2 = 4 2 x y2 = 8x
