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

Explanation

The given parabola is of the form `y^2=4ax`


On comparing, we obtain `4a=12 ` i.e., `a=3`


We know that the focal length of any point `(x,y)`on `y^2=4a`


Let the given point on the parabola `y^2=12x` be `(x,y)`
