[Closed] Bézier Curve question

Hi there

Here it is the function for the 3 points Bézier Curve to find the Beziear Curve point for .5

--based on 3 points
function Bezier3pt P1 P2 P3 Param =
(
    return ( (((1-Param)^2) * P1) + (2 * (1-Param) * Param * P2) + ((Param^2) * P3) )
)
delete objects
p1=(point pos:[0,0,0] wirecolor:red).pos
p2=(point pos:[35,0,65]wirecolor:red)
p3=(point pos:[115,0,0]wirecolor:red).pos

thebizPt = point wirecolor:green pos:(Bezier3pt p1 p2.pos p3 .5) 
--for my question I delete the P2 
delete p2

Now we have P1 P3 the param which is .5 and the Bézier point for .5 here it is the ” thebizPt “
Now my question is:
Is there any way to find the deleted P2 position?

Thanks in advance
