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