Question

Prove that a^-1/a^-1+b^-1+a^-1/a^-1-b^-1=2b^2/b^2-a^2.
Please answer.

Answer 1

Answer:

Prove that a^-1/ a^-1+ b^-1 + a^-1/ a^-1- b^-1= 2b^2/b^2-a^2 - 2661771. ... a^-1+ b^-1 + a^-1/ a^-1- b^-1= 2b^2/b^2-a^2. 2. See answers ... /b+a+ 1/a×ab /b-a. Now 'a' gets cancelled in both the numerator and the denominator.
