Bom dia Jailson!
Solução!
Esse limite pode ser calculado unicamente por substituição.
A)
![\displaystyle \lim_{x \to1} (x+1)\\\\\\
\displaystyle \lim_{x \to1} (1+1)\\\\\\
\displaystyle \lim_{x \to1} 2\\\\\\\\\
\boxed {\displaystyle \lim_{x \to1} (x+1)=2}](https://tex.z-dn.net/?f=%5Cdisplaystyle+%5Clim_%7Bx+%5Cto1%7D+%28x%2B1%29%5C%5C%5C%5C%5C%5C%0A%5Cdisplaystyle+%5Clim_%7Bx+%5Cto1%7D+%281%2B1%29%5C%5C%5C%5C%5C%5C%0A%5Cdisplaystyle+%5Clim_%7Bx+%5Cto1%7D+2%5C%5C%5C%5C%5C%5C%5C%5C%5C%0A%5Cboxed+%7B%5Cdisplaystyle+%5Clim_%7Bx+%5Cto1%7D+%28x%2B1%29%3D2%7D%0A+++ "\displaystyle \lim_{x \to1} (x+1)\\\\\\

No exercício b ,vamos fatorar a equação incompleta que esta no denominador!
![( x^{2} -1)=(x+1)\times(x-1)\\\\\
\displaystyle \lim_{x \to1} \frac{ (x^{2} +1)}{(x-1)}} \\\\\\
\displaystyle \lim_{x \to1} \frac{ (x+1)\times(x-1))}{(x-1)}} \\\\\\
\displaystyle \lim_{x \to1} (x+1) \\\\\\
\displaystyle \lim_{x \to1} (1+1) \\\\\\
\displaystyle \lim_{x \to1} 2 \\\\\\\\\\
