Divide using synthetic division $$ ( x+20 ) \div ( x-2 ) $$

The synthetic division table is:

$$ \begin{array}{c|rr}2&1&20\\& & \color{black}{2} \\ \hline &\color{blue}{1}&\color{orangered}{22} \end{array} $$

The solution is:

$$ \frac{ x+20 }{ x-2 } = \color{blue}{1} ~+~ \frac{ \color{red}{ 22 } }{ x-2 } $$

Step 1 : Write down the coefficients of the dividend into division table. Put the zero from $ x -2 = 0 $ ( $ x = \color{blue}{ 2 } $ ) at the left.

$$ \begin{array}{c|rr}\color{blue}{2}&1&20\\& & \\ \hline && \end{array} $$

Step 1 : Bring down the leading coefficient to the bottom row.

$$ \begin{array}{c|rr}2&\color{orangered}{ 1 }&20\\& & \\ \hline &\color{orangered}{1}& \end{array} $$

Step 2 : Multiply by the number on the left, and carry the result into the next column: $ \color{blue}{ 2 } \cdot \color{blue}{ 1 } = \color{blue}{ 2 } $.

$$ \begin{array}{c|rr}\color{blue}{2}&1&20\\& & \color{blue}{2} \\ \hline &\color{blue}{1}& \end{array} $$

Step 3 : Add down last column: $ \color{orangered}{ 20 } + \color{orangered}{ 2 } = \color{orangered}{ 22 } $

$$ \begin{array}{c|rr}2&1&\color{orangered}{ 20 }\\& & \color{orangered}{2} \\ \hline &\color{blue}{1}&\color{orangered}{22} \end{array} $$

Bottom line represents the quotient $ \color{blue}{ 1 } $ with a remainder of $ \color{red}{ 22 } $.
