You can put this solution on YOUR website!
Construction of several possible points for P will show that they form a line. Use a compass to make several points; and draw the line through the points with a straight edge.

That is the help to solve the problem. The ANSWER IS : Just a LINE.
You do not have enough information given to make an equation. You only have points named and a length. You have NO coordinates!!! Points only, named A, B, P. No coordinates; no equation.
