When the second power of X-2 = 0, find the second power of (x-1) / the second power of X-1 + the second power of X / x + 1

When the second power of X-2 = 0, find the second power of (x-1) / the second power of X-1 + the second power of X / x + 1

X & # 178; - 2 = 0 (x-1) & # 178; / (X & # 178; - 1) + X & # 178; / (x + 1) = (x-1) & # 178; / [(x-1) (x + 1)] + X & # 178; / (x + 1) = (x-1) / (x + 1) + X & # 178; / (x + 1) = (X & # 178; + x-1) / (x + 1) = (x + 1) / (x + 1) = 1 if you still have any questions, please ask!
