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