Simplify `(sqrt(a+b)-sqrt(a-b))/(sqrt(a+b)+sqrt(a-b))`

If x=(sqrt(a+2b)-sqrt(a-2b))/(sqrt((a+2b))+sqrt((a-2b))) , show that bx^(2)-ax+b=0

If x=(sqrt(a+2b)+sqrt(a-2b))/(sqrt(a+2b)-sqrt(a-2b)) then bx^(2)+b =

Ifx=(sqrt(a+2b)+sqrt(a-2b))/(sqrt(a+2b)-sqrt(a-2b)), thenprovetbx ^(2)-ax+b=0

Simplify (a) (sqrt(5)+sqrt(3))/(sqrt(2)) +2 (b) (sqrt3+sqrt2)/(sqrt3+sqrt6)-4

Simplify (a) (sqrt(8)-sqrt(6))^2 (b) (sqrt(5)-sqrt(8))^2

x = ( sqrt ( a + b ) - sqrt (a -b ))/( sqrt (a +b ) + sqrt (a -b )), then what is bx ^(2) - 2ax + b equal to (b ne 0) ?

(a+c sqrt(b))(2+y sqrt(b))
