My problem is from Israel Gelfand's Trigonometry textbook.
Page 9. Exercise 7: Two points, A and B, are given in the plane. Describe the set of points X such that [itex]AX^2+BX^2=AB^2.[/itex]
The attempt at a solution
Since problem asked to describe set of points X such that [itex]AX^2+BX^2=AB^2[/itex], I tried to solve for X, and got
[itex]AX^2+BX^2=AB^2\to
X^2(A+B)=AB^2\to
X^2=\sqrt{\frac{AB^2}{A+B}}[/itex]
This got me nowhere though, so I would appreciate some hints on how to approach the problem.
