SUMMARY

The discussion focuses on performing long division for the polynomial expression \( \frac{x+2}{x-1} \). The user initially arrives at the result \( 1 + \frac{4}{x-2} \) but questions its validity. The correct long division yields \( \frac{x+2}{x-1} = 1 + \frac{3}{x-1} \), confirming that the remainder is 3 when dividing \( x+2 \) by \( x-1 \). This highlights the importance of verifying polynomial division results.

So, I am wondering if there is a way to long divide $x+2 $ / $x -1$.

My result is $1 + \frac{4}{x -2}$ but does

$[1 + \frac{4}{x -2} ] * [ x - 2]$ = $x +2$

Thanks

$$\begin{array}{r}1\hspace{28px}\\x-1\enclose{longdiv}{x+2} \\ -\underline{\left(x-1\right)} \hspace{-9px} \\ 3 \end{array}$$

Hence:

$$\frac{x+2}{x-1}=1+\frac{3}{x-1}$$
