Expert Answer:

The derivation is given in your text book. Find the potential due to the two charges and add them up. since potential is a scalar quantity you only need to consider the sign and not the direction while adding them.

Besides that keep in mind that we wish to get an expression for potential that is in terms of perpendicular distance and distance between the charges. So make appropriate substitutions for this.
