If H is the harmonic mean between a and b, then show that `(H+a)/(H-a)+(H+b)/(H-b)=2`

If H be the harmonic mean between x and y, then show that (H+x)/(H-x)+(H+y)/(H-y)=2

Statement-I: If H is the harmonic mean between a and b then (H+a)/(H-a)+(H+b)/(H-b)=(1)/(2) Statement -II: If H is the harmonic mean between x and y then H=(2xy)/(x+y)

If the harmonic mean between a and b be H, then the value of (1)/(H-a)+(1)/(H-b) is-

If H is the harmonic mean between P and Q then find the value of H/P+H/Q.

If H is the harmonic mean of P and Q, then the value of H/(P)+H/(Q) is
