Subtract polynomials: $ \, \color{blue}{ 10 } \, $ , $ \, \color{orangered}{ 2 }$.
Answer
$$ \color{blue}{10} - \color{orangered}{2} = 8 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lr} & 10 \\ \color{red}{ - } & 2 \\ \hline \end{array} $$Step 2: Change ALL the signs in the second row.
$$ \begin{array}{lr} & 10 \\ \color{red}{ - } & -2 \\ \hline \end{array} $$Step 3: Combine like terms (add each column):
$$ \begin{array}{lr} & 10 \\ \color{red}{ - } & -2 \\ \hline & 12 \end{array} $$This page was created using
