Question
Add $ \, \color{blue}{ 24x^3+47x^2-4x-15 } \, $ and $ \, \color{orangered}{ 2x+5 }$.
Answer
$$ \left( \color{blue}{24x^3+47x^2-4x-15} \right) + \left( \color{orangered}{2x+5} \right) = 24x^3+47x^2-2x-10 $$
Explanation
Step 1: Write second polynomial below the first one. Making sure like terms are lined up.
$$ \begin{array}{lrrrr} & 24x^3 & 47x^2 & -4x & -15 \\ \color{blue}{ + } & & & 2x & 5 \\ \hline \end{array} $$Step 2: Combine like terms (add each column):
$$ \begin{array}{lrrrr} & 24x^3 & 47x^2 & -4x & -15 \\ \color{blue}{ + } & & & 2x & 5 \\ \hline & 24x^3 & 47x^2 & -2x & -10 \end{array} $$This page was created using
