YOUR QUESTION: What is the value of r for which (r-5)^2 = (r+2)^2?
First, solve things through so you can more easily work with the equation. Ie, multiply out (r - 5)(r - 5) and (r + 2)(r + 2).
r^2 - 5r - 5r + 25 = r^2 + 2r + 2r + 4
Simplify your equation by combining like terms and isolate r so that you can solve for it. Double check your result by sticking it in the equation and making sure both sides equal each other.
21 = 14r
You should be able to solve from there I hope.
