Answer:

\frac{1}{3x+52}

Step-by-step explanation:

We begin with the expression

\frac{\frac{1}{x^2+51x+50} }{\frac{2}{x+50}+\frac{1}{x+1} }

First, we can split this into the product of two fractions

\frac{1}{x^2+51x+50} *(\frac{1}{\frac{2}{x+50}+\frac{1}{x+1}} )

Now, we can factor the denominator of the first fraction.

\frac{1}{(x+1)(x+50)} *(\frac{1}{\frac{2}{x+50}+\frac{1}{x+1}} )

Next, we need to create a common denominator for the second fraction

\frac{2}{x+50}+\frac{1}{x+1}\\\\\frac{2}{x+50}*\frac{x+1}{x+1} +\frac{1}{x+1}*\frac{x+50}{x+50} \\\\\frac{2x+2}{(x+1)(x+50)} + \frac{x+50}{(x+1)(x+50)}\\\\ \frac{3x+52}{(x+1)(x+50)}

Now to return this portion to the denominator of the second fraction.

\frac{1}{(x+1)(x+50)} *(\frac{1}{\frac{3x+52}{(x+1)(x+50)} } )

Dividing by a fraction is the same as multiplying as the reciprocal of the fraction, so the second fraction becomes

\frac{1}{(x+1)(x+50)} *\frac{(x+1)(x+50)}{3x+52}

Now to reduce this expression by canceling out (x+1)(x+5)

\frac{(x+1)(x+50)}{(x+1)(x+50)(3x+52)}\\\\\frac{1}{3x+52}
