## The focal distance of a point on the parabola \(y^2\) = 12x is 4. Find the abscissa of this point.

Solution : The given parabola is of form \(y^2\) = 4ax. On comparing, we have 4a = 12 i.e a = 3. We know that the focal distance of any point (x, y) on \(y^2\) = 4ax is x + a. Let the given point on the parabola \(y^2\) = 12 x be (x, y). …
