Simplification of equation
is
.
<u>Step-by-step explanation:</u>
We have the following complex fraction to simplify:
![\frac{n-4}{n^{2}} - \frac{2n-15}{n} + \frac{1}{n} +3](https://tex.z-dn.net/?f=%5Cfrac%7Bn-4%7D%7Bn%5E%7B2%7D%7D%20-%20%5Cfrac%7B2n-15%7D%7Bn%7D%20%20%2B%20%5Cfrac%7B1%7D%7Bn%7D%20%2B3)
⇒![\frac{n-4}{n^{2}} - \frac{2n-15}{n} + \frac{1}{n} +3](https://tex.z-dn.net/?f=%5Cfrac%7Bn-4%7D%7Bn%5E%7B2%7D%7D%20-%20%5Cfrac%7B2n-15%7D%7Bn%7D%20%20%2B%20%5Cfrac%7B1%7D%7Bn%7D%20%2B3)
