since b is H.M. of a and c so 2/b= 1/a +1/c
so R.H.S. = 2/b
in L.H.S. = ( 2b-a-c ) / (b2 - (a+c)+ac )
now put b= 2ac /(a+c) and simplify it
you will get the same thing.
Hence the given relation is proved.

Thank u so much @ameesha6

1 upon b-a +1 upon b-c = 1/a + 1/c
b will be cut from b and then it will become 1 upon a and 1 upon b
just simply cut b and b
b will be cut from b and then it will become 1 upon a and 1 upon b
just simply cut b and b
