Question
Add $ \, \color{blue}{ -4x^2+6x+1 } \, $ and $ \, \color{orangered}{ 5x+7 }$.
Answer
$$ \left( \color{blue}{-4x^2+6x+1} \right) + \left( \color{orangered}{5x+7} \right) = -4x^2+11x+8 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrr} & -4x^2 & 6x & 1 \\ \color{blue}{ + } & & 5x & 7 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrr} & -4x^2 & 6x & 1 \\ \color{blue}{ + } & & 5x & 7 \\ \hline & -4x^2 & 11x & 8 \end{array} $$This page was created using
