Let `alpha` and `beta` be two positive real numbers. Suppose `A_1, A_2` are two arithmetic means; `G_1 ,G_2` are tow geometrie means and `H_1 H_2` are two harmonic means between `alpha` and `beta`, then

A

`(2(a^(2)+b^(2))+5ab)/(9b)`

B

`(a^(2)+b^(2))/(9ab)+5`

C

`(a^(2)+b^(2)+5(a+b))/(9ab)`

D

`(a^(2)+b^(2)+7(a+b))/(3(a+b)ab)`
