It was given this term:
\(\displaystyle \sqrt{1-(x^2+1)^2}\)
My friend got the solution \(\displaystyle -x^2\),but i think he is not right a about that,cause i believe you should first solve the quadratic binom,which is \(\displaystyle x^4+2x+1\),so my solution is:
\(\displaystyle \sqrt{1-x^4-2x-1}\) or \(\displaystyle \sqrt{-x^4-2x}\)
Im wondering who is right now,or how to solve this. Thank you!
