Determine all functions f(x) defined for all real numbers x and taking real numbers as their values such that(adsbygoogle = window.adsbygoogle || []).push({});

f(x) + f(1-x) = x^2 - 1

If i replace x by 1-x i get the same LHS and if i equate them i get x=0.5. What I need to do more is what i don't know.

Please advise

PS sorry if i used the wrong group.
