    Did I do this Hyperbola question right?
    The book asked me to find the constant differences for a hyperboka with the given foci and point on the hyperbola.

    With:

    f(1): (-13,0)
    f(2): (13,0)
    P: (5,0)


    The answer I got was 15, is that right?

    I am sorry, but I do not know what you mean by a 'constant difference'. But, the equation of the hyperbola would be:



    Does that help? I do not know where your 15 comes from.

    Can you please elaborate?
