x +1/x +1 = ???

Dear Student,

$$\begin{gathered} \mathrm{In} \mathrm{the} \mathrm{given} \mathrm{expression} \mathrm{both} \mathrm{numerator} \mathrm{and} \mathrm{denominator} \mathrm{are} \mathrm{same} . \mathrm{So}, \mathrm{they} \mathrm{will} \mathrm{cancel} \mathrm{out} \mathrm{and} \mathrm{results} 1. \\ \frac{\mathrm{x}+1}{\mathrm{x}+1}=1 \end{gathered}$$

Hope this would have clear your doubt. Do let us know in case of any further concerns.
