Answer:

x(x + 1)

Step-by-step explanation:

\frac{2x + 1}{ \frac{1}{x} +  \frac{1}{x + 1}  }

Make denominators same:

\frac{2x + 1}{ \frac{x + 1}{x(x + 1)} +  \frac{x}{(x + 1)}  }

Add the numerators:

\frac{2x + 1}{ \frac{x + 1 + x}{x(x + 1)} }

\frac{2x + 1}{\frac{2x + 1}{x(x + 1)} }

Apply the rule:

\frac{a}{ \frac{b}{c} }  =  \frac{a \times c}{b}

Therefore,

\frac{(2x + 1)\times x(x + 1))}{2x + 1}

Cancel out common factor of 2x+1:

x(x + 1)
