Subtract polynomials: $ \, \color{blue}{ -5h-2 } \, $ , $ \, \color{orangered}{ 7h+6 }$.
Answer
$$ \left( \color{blue}{-5h-2} \right) - \left( \color{orangered}{7h+6} \right) = -12h-8 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrr} & -5h & -2 \\ \color{red}{ - } & 7h & 6 \\ \hline \end{array} $$Step 2: Change ALL the signs in the second row.
$$ \begin{array}{lrr} & -5h & -2 \\ \color{red}{ - } & -7h & -6 \\ \hline \end{array} $$Step 3: Combine like terms (add each column):
$$ \begin{array}{lrr} & -5h & -2 \\ \color{red}{ - } & -7h & -6 \\ \hline & 2h & 4 \end{array} $$This page was created using
