Divide using synthetic division $$ ( 6x^{5}-4x^{2}+2x-3 ) \div ( 2x-1 ) $$
Answer
The synthetic division table is:
$$ \begin{array}{c|rrrrrr}1&6&0&0&-4&2&-3\\& & 6& 6& 6& 2& \color{black}{4} \\ \hline &\color{blue}{6}&\color{blue}{6}&\color{blue}{6}&\color{blue}{2}&\color{blue}{4}&\color{orangered}{1} \end{array} $$The solution is:
$$ \frac{ 6x^{5}-4x^{2}+2x-3 }{ x-1 } = \color{blue}{6x^{4}+6x^{3}+6x^{2}+2x+4} ~+~ \frac{ \color{red}{ 1 } }{ x-1 } $$Explanation
Step 1 : Write down the coefficients of the dividend into division table. Put the zero from $ x -1 = 0 $ ( $ x = \color{blue}{ 1 } $ ) at the left.
$$ \begin{array}{c|rrrrrr}\color{blue}{1}&6&0&0&-4&2&-3\\& & & & & & \\ \hline &&&&&& \end{array} $$Step 1 : Bring down the leading coefficient to the bottom row.
$$ \begin{array}{c|rrrrrr}1&\color{orangered}{ 6 }&0&0&-4&2&-3\\& & & & & & \\ \hline &\color{orangered}{6}&&&&& \end{array} $$Step 2 : Multiply by the number on the left, and carry the result into the next column: $ \color{blue}{ 1 } \cdot \color{blue}{ 6 } = \color{blue}{ 6 } $.
$$ \begin{array}{c|rrrrrr}\color{blue}{1}&6&0&0&-4&2&-3\\& & \color{blue}{6} & & & & \\ \hline &\color{blue}{6}&&&&& \end{array} $$Step 3 : Add down last column: $ \color{orangered}{ 0 } + \color{orangered}{ 6 } = \color{orangered}{ 6 } $
$$ \begin{array}{c|rrrrrr}1&6&\color{orangered}{ 0 }&0&-4&2&-3\\& & \color{orangered}{6} & & & & \\ \hline &6&\color{orangered}{6}&&&& \end{array} $$Step 4 : Multiply by the number on the left, and carry the result into the next column: $ \color{blue}{ 1 } \cdot \color{blue}{ 6 } = \color{blue}{ 6 } $.
$$ \begin{array}{c|rrrrrr}\color{blue}{1}&6&0&0&-4&2&-3\\& & 6& \color{blue}{6} & & & \\ \hline &6&\color{blue}{6}&&&& \end{array} $$Step 5 : Add down last column: $ \color{orangered}{ 0 } + \color{orangered}{ 6 } = \color{orangered}{ 6 } $
$$ \begin{array}{c|rrrrrr}1&6&0&\color{orangered}{ 0 }&-4&2&-3\\& & 6& \color{orangered}{6} & & & \\ \hline &6&6&\color{orangered}{6}&&& \end{array} $$Step 6 : Multiply by the number on the left, and carry the result into the next column: $ \color{blue}{ 1 } \cdot \color{blue}{ 6 } = \color{blue}{ 6 } $.
$$ \begin{array}{c|rrrrrr}\color{blue}{1}&6&0&0&-4&2&-3\\& & 6& 6& \color{blue}{6} & & \\ \hline &6&6&\color{blue}{6}&&& \end{array} $$Step 7 : Add down last column: $ \color{orangered}{ -4 } + \color{orangered}{ 6 } = \color{orangered}{ 2 } $
$$ \begin{array}{c|rrrrrr}1&6&0&0&\color{orangered}{ -4 }&2&-3\\& & 6& 6& \color{orangered}{6} & & \\ \hline &6&6&6&\color{orangered}{2}&& \end{array} $$Step 8 : Multiply by the number on the left, and carry the result into the next column: $ \color{blue}{ 1 } \cdot \color{blue}{ 2 } = \color{blue}{ 2 } $.
$$ \begin{array}{c|rrrrrr}\color{blue}{1}&6&0&0&-4&2&-3\\& & 6& 6& 6& \color{blue}{2} & \\ \hline &6&6&6&\color{blue}{2}&& \end{array} $$Step 9 : Add down last column: $ \color{orangered}{ 2 } + \color{orangered}{ 2 } = \color{orangered}{ 4 } $
$$ \begin{array}{c|rrrrrr}1&6&0&0&-4&\color{orangered}{ 2 }&-3\\& & 6& 6& 6& \color{orangered}{2} & \\ \hline &6&6&6&2&\color{orangered}{4}& \end{array} $$Step 10 : Multiply by the number on the left, and carry the result into the next column: $ \color{blue}{ 1 } \cdot \color{blue}{ 4 } = \color{blue}{ 4 } $.
$$ \begin{array}{c|rrrrrr}\color{blue}{1}&6&0&0&-4&2&-3\\& & 6& 6& 6& 2& \color{blue}{4} \\ \hline &6&6&6&2&\color{blue}{4}& \end{array} $$Step 11 : Add down last column: $ \color{orangered}{ -3 } + \color{orangered}{ 4 } = \color{orangered}{ 1 } $
$$ \begin{array}{c|rrrrrr}1&6&0&0&-4&2&\color{orangered}{ -3 }\\& & 6& 6& 6& 2& \color{orangered}{4} \\ \hline &\color{blue}{6}&\color{blue}{6}&\color{blue}{6}&\color{blue}{2}&\color{blue}{4}&\color{orangered}{1} \end{array} $$Bottom line represents the quotient $ \color{blue}{ 6x^{4}+6x^{3}+6x^{2}+2x+4 } $ with a remainder of $ \color{red}{ 1 } $.
