(1)√x-a/x-b + a/b = √x-b/x-a + b/a, b not equal to a, then value of x is

Question

(2) if x = 2√24/√3+√2 then value of x+√8/x-√8 + x+√12/x-√12 .

(3) if a = 2+√3/2-√3 & b = 2-√3/2+√3 then value of (a square + b square + ab) =

Answer 1

(1) depending on a and b, x is either
ab/(a+b) or (a^2+ab+b^2)/(a+b) = (a^3-b^3)/(a^2-b^2)

(2) value is 2

(3) value is 195

Answer 2

thanks steve but please explain it briefly
