Given two numbers: [tex] A + \sqrt{A^2 - B^2}[/tex] and [tex] U + \sqrt{U^2 - V^2}[/tex] OBS: A, B, U and V are real numbers.
I want sum it and express the result in the same form: [tex] A + \sqrt{A^2 - B^2} + U + \sqrt{U^2 - V^2} = x + \sqrt{x^2 - y^2}[/tex] So, x depends of A and U. And y depends of B and V:
[tex] x = x(A, U)[/tex] [tex] y = y(B, V)[/tex] Do have any ideia about how do it?
PS: A is the arithmetic mean of the roots of the quadratic equation and B is the geometric mean. Is a nice expression for the quadratic formula!
