Divide using synthetic division $$ ( 7x-30 ) \div ( 6 ) $$

The synthetic division table is:

$$ \begin{array}{c|rr}0&7&-30\\& & \color{black}{0} \\ \hline &\color{blue}{7}&\color{orangered}{-30} \end{array} $$

The solution is:

$$ \frac{ 7x-30 }{ x } = \color{blue}{7} \color{red}{~-~} \frac{ \color{red}{ 30 } }{ x } $$

Step 1 : Write down the coefficients of the dividend into division table.Put the zero at the left.

$$ \begin{array}{c|rr}\color{blue}{0}&7&-30\\& & \\ \hline && \end{array} $$

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

$$ \begin{array}{c|rr}0&\color{orangered}{ 7 }&-30\\& & \\ \hline &\color{orangered}{7}& \end{array} $$

Step 2 : Multiply by the number on the left, and carry the result into the next column: $ \color{blue}{ 0 } \cdot \color{blue}{ 7 } = \color{blue}{ 0 } $.

$$ \begin{array}{c|rr}\color{blue}{0}&7&-30\\& & \color{blue}{0} \\ \hline &\color{blue}{7}& \end{array} $$

Step 3 : Add down last column: $ \color{orangered}{ -30 } + \color{orangered}{ 0 } = \color{orangered}{ -30 } $

$$ \begin{array}{c|rr}0&7&\color{orangered}{ -30 }\\& & \color{orangered}{0} \\ \hline &\color{blue}{7}&\color{orangered}{-30} \end{array} $$

Bottom line represents the quotient $ \color{blue}{ 7 } $ with a remainder of $ \color{red}{ -30 } $.
