Question

Find the standard form of the equation of the parabola with a focus at (-2, 0) and a directrix at x = 2.

Answer 1

(y - 0)^2 = 4(-2)(x - 0)?? P not equal to -2?

Answer 2

assume a point on parabola p(x,y)

Answer 3

let s be the focus with co ordinates (-2,0) and M be the point on the directrix
