\frac{2un}{1+un}-un
You asked:
Evaluate the expression: \(\frac{2 u n}{1 + u n} - u n\)
MathBot Answer:
Evaluated
\(\displaystyle \frac{2 u n}{1 + u n} - u n = - n u + \frac{2 n u}{n u + 1} \)
Expanded
\[\frac{2 u n}{1 + u n} - u n = - n u + \frac{2 n u}{n u + 1}\]
Factored
\[\frac{2 u n}{1 + u n} - u n = - \frac{n u \left(n u - 1\right)}{n u + 1}\]
