Question
Subtract polynomials: $ \, \color{blue}{ 16x+10 } \, $ , $ \, \color{orangered}{ 6x-2 }$.
Answer
$$ \left( \color{blue}{16x+10} \right) - \left( \color{orangered}{6x-2} \right) = 10x+12 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrr} & 16x & 10 \\ \color{red}{ - } & 6x & -2 \\ \hline \end{array} $$Step 2: Change ALL the signs in the second row.
$$ \begin{array}{lrr} & 16x & 10 \\ \color{red}{ - } & -6x & 2 \\ \hline \end{array} $$Step 3: Combine like terms (add each column):
$$ \begin{array}{lrr} & 16x & 10 \\ \color{red}{ - } & -6x & 2 \\ \hline & 22x & 8 \end{array} $$This page was created using
