what is the work done a bringing a charge from infinity to a point P, if the point P is 5m to the positive y-axis from a charge A(5uC) which is 3m to the left of another charge B(-2uC)?

I'm sorry its 4m to the positive xaxis from point A. I started by calculating the electric potential and potential energy at point P.. but I don't know which distance to use in solving for the workdone. is it the distance from A or B or both.
