Question 273159: Find the value(s) of x so that the distance between the points A(3, 5) and B(x, 8) is 5 units.
i have tried using the distance formula AB = (x2 – x1)2 + (y2 – y1)2 with a square root on all of the equation and substituting the values and working back using the balance method, but I got the wrong answer.
the answer is 7 or -1. How can I solve this question?

^2\ +\ (y_1\ -\ y_2)^2})
^2\ +\ (5\ -\ 8)^2})
Square both sides:
^2\ +\ (5\ -\ 8)^2)
Simplify:
Factor and solve the quadratic. Both roots are valid solutions.
