Divide using synthetic division $$ ( 8x^{2} ) \div ( x-2 ) $$
Answer
The synthetic division table is:
$$ \begin{array}{c|rrr}2&8&0&0\\& & 16& \color{black}{32} \\ \hline &\color{blue}{8}&\color{blue}{16}&\color{orangered}{32} \end{array} $$The solution is:
$$ \frac{ 8x^{2} }{ x-2 } = \color{blue}{8x+16} ~+~ \frac{ \color{red}{ 32 } }{ x-2 } $$Explanation
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.
$$ \begin{array}{c|rrr}\color{blue}{2}&8&0&0\\& & & \\ \hline &&& \end{array} $$Step 1 : Bring down the leading coefficient to the bottom row.
$$ \begin{array}{c|rrr}2&\color{orangered}{ 8 }&0&0\\& & & \\ \hline &\color{orangered}{8}&& \end{array} $$Step 2 : Multiply by the number on the left, and carry the result into the next column: $ \color{blue}{ 2 } \cdot \color{blue}{ 8 } = \color{blue}{ 16 } $.
$$ \begin{array}{c|rrr}\color{blue}{2}&8&0&0\\& & \color{blue}{16} & \\ \hline &\color{blue}{8}&& \end{array} $$Step 3 : Add down last column: $ \color{orangered}{ 0 } + \color{orangered}{ 16 } = \color{orangered}{ 16 } $
$$ \begin{array}{c|rrr}2&8&\color{orangered}{ 0 }&0\\& & \color{orangered}{16} & \\ \hline &8&\color{orangered}{16}& \end{array} $$Step 4 : Multiply by the number on the left, and carry the result into the next column: $ \color{blue}{ 2 } \cdot \color{blue}{ 16 } = \color{blue}{ 32 } $.
$$ \begin{array}{c|rrr}\color{blue}{2}&8&0&0\\& & 16& \color{blue}{32} \\ \hline &8&\color{blue}{16}& \end{array} $$Step 5 : Add down last column: $ \color{orangered}{ 0 } + \color{orangered}{ 32 } = \color{orangered}{ 32 } $
$$ \begin{array}{c|rrr}2&8&0&\color{orangered}{ 0 }\\& & 16& \color{orangered}{32} \\ \hline &\color{blue}{8}&\color{blue}{16}&\color{orangered}{32} \end{array} $$Bottom line represents the quotient $ \color{blue}{ 8x+16 } $ with a remainder of $ \color{red}{ 32 } $.
