Calculating the touching point

A parabola has been created with a string construction from the control points, AA, BB and CC.
A=(2,12)A = (2, 12)
B=(2,2)B = (2, 2)
C=(12,2)C = (12, 2)
Point QQ is on the line ABAB at (2,6)(2, 6).
Point RR is on the line BCBC at (8,2)(8, 2).
Line QRQR touches the parabola at point PP.
Given that the ratio of AQ:ABAQ : AB equals the ratio of BR:BCBR : BC, what are the coordinates of PP?
PP = ((
