Question
Subtract polynomials: $ \, \color{blue}{ 9c+5 } \, $ , $ \, \color{orangered}{ 9c+3 }$.
Answer
$$ \left( \color{blue}{9c+5} \right) - \left( \color{orangered}{9c+3} \right) = 2 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrr} & 9c & 5 \\ \color{red}{ - } & 9c & 3 \\ \hline \end{array} $$Step 2: Change ALL the signs in the second row.
$$ \begin{array}{lrr} & 9c & 5 \\ \color{red}{ - } & -9c & -3 \\ \hline \end{array} $$Step 3: Combine like terms (add each column):
$$ \begin{array}{lrr} & 9c & 5 \\ \color{red}{ - } & -9c & -3 \\ \hline & 18c & 8 \end{array} $$This page was created using
