not writing question again....
= (1/a) / (1/a + 1/b) + (1/a) / (1/a - 1/b)
= (1/a) / (a + b)/ab + (1/a) / (b - a)/ab
= (ab/a) /(a + b) + (ab/a) / (b - a)
= b / ( b + a ) + b / ( b - a )
= {b(b - a) + b ( b + a)}/ (b + a) (b - a)
= (b^2 - ab + b^2 + ab)/b + a) (b - a)
= 2 b^2 / b + a) (b - a)
RHS proved
